1. Are all chillers made the same?
No, there are numerous ways to build a chiller using numerous materials. Some have no reservoir while others have plastic or stainless steel reservoirs. There are probably as many features as there are on new cars.
2. I was told by a chiller company that doesn’t manufacture a low temp chiller especially for breweries that you can use any chiller for breweries. Is that correct?
While there is some truth to what he says it isn’t practical truth. If you use a chiller that isn’t designed for low temp it may reach set point, however normally this is achieved by oversizing to make up for the inadequacies of the standard temp chiller. The cost per BTU purchased and the cost to produce BTU will be much higher. A low temp chiller has a refrigerant charge for low temps, a water pump that operates efficiently at low temps and the chiller plus plumbing is well insulated to different degrees by different manufacturers, some more than others.
3. What is the difference between a brewery chiller and a standard chiller?
There are only a few companies that design true brewery chillers, those companies such as Pro Chillers, GD Chillers, and Chillking Chillers will tell you there is a big difference between standard chillers and low temperature chillers designed for breweries. At times a different coolant pump is required because low temps make lubricants sluggish. All three manufacturers have their preferred method of removing heat. The reservoirs are also well insulated. Some use stainless steel reservoirs while others use plastics. In the opinion of Chillking the most important component is the evaporator. This is where the heat is removed from the coolant. Study the brands and find the one that best suits your needs.
4. Are all brewery chillers of the same basic footprint?
Again it depends upon design, some companies build a horizontal version and a vertical version of a chiller model that has the same performance. Normally they use the same components in a vertical as they do a horizontal, they just build upwards.
5. Do all chiller companies use a standard industry design?
No, although some may appear the same this is because the laws of thermal dynamics never change. You may notice a difference in line size within the condenser or different tanks. But the base is always the same, condenser, evaporator, compressor. The compressor moves the refrigerant, the evaporator removes heat from the environment it’s in, and the condenser discharges the heat absorbed by the evaporator. There is more to it but all follow this basic design.
6. Are the warranties the same throughout the industry?
Each company has a standard warranty for their product. Most companies use Copeland Compressors. Copeland gives a 1 year warranty, anything beyond this is by the chiller manufacturer and their belief in the life of their compressors based on the design of their chiller. The most important part of the warranty in the opinion of Chillking is the compressor portion. If a company has no compressor issues it is very easy to offer a long term warranty.
7. I have a fast food restaurant with several pieces of equipment. Why does a six ton Chillking provide enough cooling for more than six tons of equipment?
Chillking has been designing, building, and installing chillers for fast food and yogurt for over twenty years. We understand the business better than any chiller company. We use a very large reservoir in our chillers, this gives you reserve capacity for starting several pieces of equipment. When we first got into the fast food business we bought very expensive equipment for long term testing of ice cream, ice, and slush machines. We know the cycle and run times of each piece of equipment by manufacturer. If we size a system, we guarantee our sizing. Be it restaurant, yogurt, store, or brewery, we stand behind our sizing. Our guarantee is based on the information given to us by the customer at the time of sizing the equipment.
8. How many amps does a chiller circuit require? Do you build single phase and three phase chillers? If so what voltages do you build chillers for?
Chillking builds chillers in single phase and three phase. We build in most any voltage there is. We build low voltage chillers in 24v and 48V, then more traditional 1 Phase in 120v to 208v and 240v. In 3 phase we build 208v, 220v, 230v, 240v, 460v-480v, and 575v-600v. Ask for other voltages. The amp draw of a chiller depends on the size of chiller and voltage. Check our specs page for amp draws of models.
9. Are your chillers built for indoors or outdoors?
All Chillking chillers and Chillking coolers are built to be used outdoors or indoors. Any of our outdoor chillers can be used inside also however check with your sales associate at your dealer, there must be adequate space to discharge the heat into.
10. Where does the chiller need to be located?
Many are located on rooftops. If location on a roof is planned it is important to check with the structural engineer for weight loads. Your chiller can be located at ground level if you prefer. Be sure to check with Chillking for proper concrete pad thickness or rooftop robber vibration pads. If located at ground level and your equipment is higher than the chiller you must have valves on the main supply and return lines to prevent back flush and overflow.
11. How much glycol do I use? What type?
Chillking only recommends and sells a high quality food safe Propylene glycol (PG). It has all the additives and ingredients to keep your system clean and operating for years. We sell PG in 55 gallon drums of 95% pure PG, the other 5% is the additives and cleansers to keep you operating. We do not recommend ethylene glycol unless industrial applications. The amount to add is based on your operating temperature and upon the ambient conditions during winter. Whatever is the lowest temperature is the determining factor.
12. Does the pump need to run 100% of the time?
No it doesn’t, however in most cases you use more energy by starting and stopping your pump. Also, we use a bypass in the pump to increase BTU capacity. I can’t give away secrets however only Chillking guarantees 110% of the rated tonnage of the chiller at 90F ambient and 50F LWT. This drastic increase in BTU is assisted by pump boost. In some cases it is better to cycle the pump. Ask your Chillking Pro.
