Use your existing glycol system to cool your cellar
Eliminates the need to purchase an entirely separate refrigeration system
MR series fan units offer quieter operation compared to the SD-S units
Sized for well-insulated rooms up to 3,500 ft³
Made in Germany by Kreyer

Cool your cellar using your existing glycol system. Save energy and money! These units work under the same principles as standard refrigeration but use cooled glycol instead of cooled refrigerant gas, eliminating the need to have a separate refrigeration system. It is a fantastic use of your glycol system for a majority of the year when typically glycol systems are on but are being sporadically called upon. Glycol systems do need to be sized to accommodate both these fan units and peak duty during the crush to be able to accommodate all tasks at once.

Glycol from your main glycol chiller is recirculated through these fan units. Aluminum fins act as heat exchangers drawing heat out of your room as the fins are cooled by the glycol. If you have a Kreyer chiller/heater you can even heat a space in cold weather environments.

The heat exchangers inside the units are made from corrugated aluminum fins and internally grooved copper tubes. The white ABS casing looks great. Because of its rounded corners it has no water retaining areas favorable to germ development. Units are outfitted with stainless steel screws and show no sharp, cutting edges.

Fan Unit Temp Control Upgrades:

1/2 in. Solenoid Valve - Allows or blocks flow of glycol through the fan unit. Needs to be connected to a Controller to function. A filter is recommended to protect the solenoid.
1/2 in. Solenoid Filter - protects the solenoid valve from any particulate or sediment.
Glycol Fan Control Unit - Set a specific temperature on this controller and it will open and close the solenoid valve.
Solenoid Connection Cable - This 2 meter long cable is required to connect the Solenoid Valve & Control unit.

Inlet and Outlet: 3/4" Male BSP

What does "cool" mean? What kind of temps can I get a 10x10x10 walking cooler down to?

Tyson Crudup on Oct 5, 2019

BEST ANSWER: Hi Tyson, the Kreyer Fan Units will be able to transform a room into a cold room when used with a glycol chiller. As far as how cold your room can get will depend on the size of your glycol chiller and fan combination.

Nice unit, couple of details to note

Great fan unit. Lightweight. Low power A/C addition to your glycol system. I have this above my fermenters to help keep the area cool.
There are a couple of things to know here:
1) My fan unit was 3/4" EU pipe thread
- Not 1/2" and not tapered like NPT, requiring a grommet and an adapter, or a hot water heater hose which worked well.
2) These run on European 230V, which is not the same as US 240V
- US 240V is 2-120V legs out of phase, a neutral, gnd
- EU 230V is 1-230V leg, and a neutral, gnd
- I had to buy a step-up transformer to get the 230V leg
3) The fans are pullers, not pushers, so the air will enter the grille and exit out the evaporator side. This was a surprise to me, and in my opinion, not very obvious in the documentation. Since these are AC motors, it's not like you can just reverse the polarity, flipping the prop doesn't work either. I overcame this by disassembling the motors and turning the stator upside-down. Be careful if you do this because the winding wire is fragile and needs to be shielded from the housing.

Hope this helps if you're going with these units
