Installation of the Immersion Mining Enclosure & ICP40 Dry Cooler

1.Your Immersion Enclosure + ICP40 Dry Cooler kit will be shipped on a single europallet (120×80). It contains all the components necessary to set everything up. Most of the elements and accessories are hidden inside the immersion tank and the dry loop filling pump package

2.Remove the wrap carefully and watch out not to damage any elements of the system.

3.Your Immersion Enclosure + ICP40 Dry Cooler kit will be shipped on a single europallet (120×80). It contains all the components necessary to set everything up. Most of the elements and accessories are hidden inside the immersion tank and the dry loop filling pump package

4.Take the ICP40 off the pallet and put it down horyzontally on its rubber anti-vibration feet. If the device doesn’t have any, make sure to attach them before placing the equipment on the ground.

5.Remove screws that secure a cover of pump compartment. Take off a side panel, marked with a DCX sticker. Removing the panel might require a little effort, so grab a black handle tight and take the lid off.

Pump compartment consists of:

 

  • circulation pump
  • switchgear with two fuses (W for fans and P for pump)
  • adaptive fan controller
  •  controller sensor
  • one-way valve for loop filling
  • vent valve
  • ball valve for maintenance works
  • in- and outflow collector

6.Beside maintenance works, especially when the system is fully loaded and operational, the pump compartment must be completely closed. Otherwise fans would suck air through pump compartment, instead of dry cooler’s finpack, as it’s supposed to be

7.Place the dry cooler outside your facility, preferably on a northern wall of the building. Keep at least 16-inch distance between the device and the wall. Recommended distance is 40 inches though.

8.Establish a pipe connection between the immersion enclosure and the dry cooler without bending piping too much, so that no flow restrictions take place. Both components may be installed on different levels (eg. the tank stays in the cellar and the dry cooler is on the ground floor). Due to the integrated air vent, the top part of the dry cooler should be set up higher than the upper lid of the enclosure.

9.Find a 10m-long rubber hose in the package, cut ends and attach it to saw-shaped hose fittings, pushing it all the way down. Use GBS clamps to fasten the hose at the very base of the fitting, not further than 2mm. Caution: ends of the rubber hose must be cut clean, without spikes or bumps.

10.Make sure pipes are connected the right way:

 

  • Dry Cooler’s inflow is under the pump, outflow is on the right side of the pump compartment.
  • Immersion enclosure’s inflow is on the bottom of the heat exchanger, outflow is just above it.

1.Filling the system

1.1. Unpack an orange dry cooler loop filling hand pump, take everything out from the inside and attach the removable lever. The pump has 2 valves: V1 (closer to the pressure gauge), V2 (further away from it) and the manometer itself.

1.2. In order to prepare the system for work:

 

  • attach the hand pump hose to the one-way valve
  • there are two valves and a pressure gauge on the pump’s jacket. In order to fill the loop, turn V2 clockwise and V2 counterclockwise, as much as possible.
1.3 Red arrow of the manometer shows maximum instantaneous pressure in the system. While releasing the pressure, remember about resetting the red arrow’s position by turning it to the left. After setting it to zero, the whole setup must be filled with operational pressure of up to 6 bar. A black outer scale of the manometer shows pressure in BAR.
1.4. Fill the pump container with either demineralized or distilled water. About 50 litres of fluid are needed to fill the loop of ICP40.
1.5. The kit includes a Febi fluid concentrate with special additives for cooling systems. Pour half of this bottle into demineralized water.
1.6. Unscrew the cap of the one-way valve, and screw the nipple in (you will find on the hose of the loop filling hand pump).
1.7. Before filling the loop, open the valve above the pump (red handle on the pipe).
1.8. After filling the System to a maximum of 10 bar, briefly open the vent valve at the top and release air. When pumping up the system, you will have to remove excessive air from the system over and over again.

2.Venting the system

2.1. The ICP40 has a vent in the upper part of the drycooler, located just above the pump. Use it to vent the system. In order to do that you’re going to need to:

 

  • Turn the valve counterclockwise for a while to release excessive air from the loop. A small amount of water may also sprinkle out during this operation, but this is totally normal. This action may  be repeated many times during the setup and launch of the loop.
  • After filling the loop (Dry Cooler – Enclosure) turn the pump on. It can be done by lifting the P fuse in the drycooler switchboard. Run the pump without the fans (W) to hear the hydraulics work and vent the system properly.
  • To release air from the drycooler’s recesses, you can shake and tilt the device several times.
  • After a long while, you’re going to have to vent the system again by briefly opening the vent valve.
  • After launching miners and warming up circulation, venting will have to be done over. When the pump is running smoothly and you can’t hear any air bubbles in the system, you may consider the loop to be properly vented.

3.Electrical connection of the Immersion Mining Enclosure & ICP40 Dry Cooler.

3.1. Connect the drycooler and the enclosure to power supply. All our enclosure components use EU / Asian standard: 1×230V (+6%/-10%), 50Hz. So they will work in the 220-240VAC (single-phase) range (do not mix that with 2 phase 220V US standard).
3.2. Power supply and power consumption of the devices:

  • Circulation pump on the enclosure – (180W)
  • Circulation pumps and fans in ICP40 Dry cooler Pump – 180W max. Fans 2x 380W / 1.75A max = 940W per ICP40 maximum).
3.3. If needed you may use voltage converter that will convert USA 110V to desired EU/ ASIA voltage (Example https://www.amazon.com/gp/product/B002IU36J2). You’ll need conversion to EU/Asia 220-240 VAC with at least double capacity than the connected component power for continuous use.

4.ICP40 fan operating modes:

4.1. ICP40’s fans can work in constant mode – at 100% speed, or in adaptive mode – in this case their speed is controlled by a special controller:

  • In the constant mode, turn on the fan (fuse W up), but the speed controller should be turned off (position 0) at the same time.
  • In adaptive mode, the controller should be turned to position 1, and the W fuse should be down. In this case fan speed depends on the temperature of the fluid flowing out of the dry cooler, which is measured by a sensor mounted on the drain manifold

5. Programming feature of the ICP40 Adaptive Fan Controller

Once being switched on, the controller starts working in auto mode. When the heat sensor detects an excess of switch- on temperature threshold, fans start working at minimum speed. Fan speed grows linearly according to heat increase, until they reach maximum speed activation temperature. Fans keep working at max speed when heat exceeds that level. In case of emergency, such as heat sensor failure, fan speed jumps on maximum level automatically.

Controller setup

Set the main switch to “0” position. Next, set it to “I” while holding “P” button. Release “P” when you see two horizontal lines on the screen. “Configuration” and “Maximum fan speed” lights will start blinking.Set up maximum fan speed by pressing “+” and “-” buttons. When you press “P” shortly, “Minimum fan speed” light will switch on. This mode allows to set up minimal fan speed, which will keep it running most of the time without breaks. CAUTION: Keep in mind that when minimum speed is too low, it may harm fan engine. Pressing “P” again will activate the third light, which corresponds to the maximum fan speed activation temperature. Pressing it one more time leads to activation of the forth light, which allows to configure fan switch-on temperature. When this value is set to 30°C fans automatically launch when the sensor detects temperature exceeding this threshold. If heat decreases by more than 1°C (falls below 29°C) the fan engine stops. In order to save settings, press and hold “P” button for a few seconds. Release the button when all lights start blinking, so that the fan controller restarts with new settings applied. It’s possible to modify any parameter and save changes any time.

Single Immersion Cryptomining Enclosure Installation Examples

All our systems are built for easy scale from single enclosure, to multiple racks. We also took into account flexibility of the solution. Our enclosures may be installed with a simple “Ikea style” setup or connected to facility heating / cooling loop at your home, garage, workshop or business. Please see simplified drawings of possible installations setups.

Designed for ease of use and simplicity. Immersion is easy! You get one enclosure, a dry cooler and 10 meters of tubing. The setup is quick and does not require any special skills or professional knowledge.
The enclosure should be placed inside of your workshop / garage or facility, and the dry cooler – outside, so it has access to fresh air. We use a large 24-30kW rated dry cooler with dual fans and temperature controller. With regards to the enclosure, you need to take into account that it will be quite heavy when filled with hardware and heat transfer fluid, so it should be placed on the ground.
We sell those systems either with or without 150L of Heat Transfer fluid. Miners should be placed tightly in Immersion Mining Enclosure, gaps between the miners avoided, empty spaces filled with containers, so the fluid will be forced to go through the miners or GPU cards and not around.

The whole setup takes just connecting two components with tubing, filling the enclosure with fluid, so it goes over the dividing chamber and starts the system. Fans on dry coolers will start when the fluid temperature goes over 40C/104F. The miners should be placed vertically inside the enclosure and fan emulators or custom firmware should be used. That’s it! We will support you on setup and provide video manuals on connecting and starting the system.

DCX Immersion Mining Enclosure Single Loop

The same Immersion Enclosure but delivered with hydraulic fittings, a brazed plate heat exchanger and an energy-efficient pump system, which is almost. If you have facility (home, office, workshop) heating / cooling loop, you can connect our enclosure and reuse the heat from miners. Providing continuous 40-50C /104-122F to supply home installation in cold season.
An ideal solution for colder regions to supply heat to radiators, pools, jacuzzi or floor heating. Still, for hot season you can purchase a drycooler which will extract excess heat. The most flexible system you can get and install.

Ideally connected by local home installations / heating contractor, but it may be also configured by any DIY type person with 1 inch connectors from our plate heat exchanger to home buffer tank.

DCX Immersion Mining Enclosure Dual Loop

A dual loop system is an ideal solution for colder regions to supply heat to radiators, pools, jacuzzi or floor heating. Still, for hot season you can purchase a dry cooler, which will extract excess heat. The dry-cooler can be connected to a home water loop using own auxiliary low-power pump or without it, using just facility flow. The most flexible system you can get and install.

Ideally connected by local home installations / heating contractor, but it may be also configured by any DIY type person with 1 inch connectors from our plate heat exchanger to home buffer tank.

Immersion Cryptomining Rack System Installation Examples

All our systems are built for easy scale from a single enclosure, to multiple racks. If you need more than a single enclosure we offer scale-up rack systems. Using Universal Enclosures as building block they occupy 1 sq. meter of space, but provide a huge 24xS17 or 20 M20s density. Those are connected to external larger dry cooler, or facility heating/cooling loop at your home, garage, workshop or business. Please see simplified drawings of possible installations setups.

Our rack system is based on Dual loop Universal Immersion Mining Enclosures with custom aluminum frame and table which allows middle enclosures to be slide out from the rack for maintenance. Originally with 3 enclosures but might be stacked to 4 enclosures. This system may be delivered with two types of heat rejection: single enclosure – single loop with dry cooler, or all enclosures connected to facility loop. We recommend the second solution which allows for greater flexibility and scalability.

In scale-up scenario one rack with 3 or more dual loop enclosures connected in series. Each enclosure has own brazed plate heat exchanger and low power, energy-efficient pump. Heat transfer fluid circulates only in enclosures. On the other side, we would use a typical water/glycol heating loop that may reuse the heat for facility purposes or reject the heat to a larger 50-70-100kW dry cooler. Both solutions provide unparalleled density and scalability.

We suggest that such a rack system or dry cooler should be installed by a local contractor which specializes in heating/cooling systems.

DCX Immersion Mining Rack Dual Loop

Rack system transfers from 50 to 70kW of heat so it requires larger heat rejection device. We suggest dry cooler as 50-60C fluid can be easily and cost-effectively extracted to air without air conditioning, chillers and water towers. The 50-100kW range dry-cooler will be connected to the home or facility loop using own auxiliary low-power pump.

Dry coolers are flexible and easy to size and may be upgraded to any heat load by adding more modules in series. They will use convection for most of the time and are simple to operate.  When properly sized for the local climate, the fans on a dry cooler should only be operated for no more than 20% of the time and only during the hottest time of day. They also require very low maintenance, so they do have lowest operation cost from any other heat rejection methods.

Ideally connected by local home installations / heating contractor which can help you to size and maintain your installation in the long term.
