What’s the lowest the controller/chiller will go?
This is by far the most common question, and it is by far the hardest to answer. There is no blanket statement that applies.
Water Chillers: Our lowest recommended operating temperature is 45F. Can the unit go lower? – Sure, on 5 gallons we tested to 36F, however our recommended lowest set point is 45F. That does not mean the chiller is guaranteed to reach 45F. The temperature the chiller is capable of reaching is completely dependent on your setup (Volume / Heat Load / Goal Temp / Ambient Conditions /etc.)
Glycol Chillers: Just like the standard chillers the lowest temperature the glycol chiller is capable of is dependent on the heat load. Our lowest recommended setting is 5F. In testing it maxed out at -14F with no load.
Is there a reservoir built in / what size is it?
Water Chiilers: There is no built in tank or reservoir, the internal piping and exchanger holds less than 1/2 gallon
Glycol Chillers: 1/2HP has a 2 gallon bath, 1HP has a 3 gallon bath, the commercial line has a 30 gallon reservoir
Does it function as a heater too?
No, our chillers only have cooling capabilities.
How loud is the chiller?
The chillers are fairly quiet, the general feedback is – they are quieter than expected. The dBA rating are provided on the individual product page if available.
How much heat does the chiller put out?
That depends. The function of a chiller or any refrigeration device is to move heat from one area to another. In a water chiller it is moving heat from the water to the air. The amount of heat going into the air is directly related to how much heat needs to be removed from the water.
Does it need to be ventilated
Some ventilation is required, a chiller cannot properly function if locked in a small cabinet or closet. Remember the chiller is taking the heat out of the water and putting it into the air, it can only put so much heat into the air. When it can no longer put excesses heat into the air because the air is already too hot, the chiller won’t be able provide any additional cooling. It is recommend to provide as much ventilation as possible. The cooler the air is around the chiller the less the chiller will run, making it more efficient.
Can it be installed outside?
Our standard chillers need to be protected from rain/water that could damage the controller or internal electronics. If properly protected from rain/water an outside installation would be ok. Our commercial line is outdoor ready.
Is there a built in pump?
No, you will need to supply your own pump.
What size/type pump should I use?
Water chillers: We typically recommend using a 500gph-950gph pump to achieve a minimum measurable flow of at least 250gph. A pump needs to be sized to compensate for loss of flow due to pipe length, fittings, and head height. A common misconception is that the size of a pump determines how efficient the chiller will be. The pump size plays little or no role in how effective a chiller is, the main purpose of providing a recommend pump size is to ensure the consumer has enough flow to not freeze water in the chiller, and not too much flow to over pressurize the chiller. Typically submersible pumps are used due to simplicity, however most any pump providing the required flow would be suitable. One exception is a diaphragm pump, do not use a diaphragm pump.
Glycol Chillers: We carry a line of glycol pumps that are recommended for our glycol chillers, space is limited in the glycol bath so sourcing a different pump may be problematic due to size restrictions.
Commercial Water Chillers: We recommend maintaining a minimum measurable flow of 900gph though the chiller. Due to the variety of applications the pump size will vary considerably to achieve this flow rate.
Can I use glycol with it?
Any of our chillers can operate with water or glycol. With our glycol chillers it’s typical to use 40% to 50% glycol to water mix, but you can run any mix ratio you wish to.
Can you move the inlet, outlet, or controller to a different side or location?
No, this would require a complete redesign of the chiller.
Do you offer anything smaller than 1/2HP?
1/2HP is the smallest we offer. It never hurts to oversize the chiller. One common misconception is that a bigger chiller will use more electricity. A larger chiller will use more electricity while on, but it will run a lot less. In the end the work being preformed is the same regardless of chiller size, therefore the electricity to do the work will be pretty much the same as well.
Can you make a 120v/220v/240v/etc. version?
The voltage listed on the product page is the only voltage available for that product.
What is your return policy?
Within 30 days of delivery. Shipping is non-refundable. There is a 20% restocking fee on all returns. Chillers are not the type of product to “try” and then return if it’s the wrong size or doesn’t work the way you thought it would. Shipping is expensive and units must be inspected and serviced upon return. If you have any doubts about sizing it’s better to ask for help prior to your purchase. Please note: a DOA chiller is covered under our warranty not the return policy.
