Frequently Asked Questions
What is glycol?
Glycol is an antifreeze. There are two main types of glycol: propylene and ethylene. In food applications propylene glycol is used as it is non-toxic. Ethylene glycol is typically used in industrial applications.
What is the proper glycol to water percentage or mixture?
G&D Chillers recommends a 35% Inhibited Propylene Glycol to 65% water (24.75 brix). Measure the solution using a glycol refractometer.
Where do i set or install my chiller?
The chiller location needs to be on a flat, level surface, typically outside on a concrete pad. It can be installed on a roof, but this will require a roof capable for supporting the chillers operating weight. Make sure you contact your local municipality for any city and state regulations.
Does chiller placement matter?
Yes! Be mindful of air flow when deciding where to place the chiller. Overhangs can prevent air rejection, so Vertical Air series chillers should not be placed underneath them. Similarly, there should be no obstructions in front of the exhaust side of horizontal discharge units. Refer to your chiller manual for more detail.
What is the lead time to build my new chiller?
This varies depending on the time of year. A typical lead time is 4-6 weeks.
How much maintenance does a package chiller require?
Maintenance is minimal. Measure the glycol mixture quarterly throughout the year. Keep the condenser clear of obstructions and free of leaves and debris. It is good to establish a relationship with a qualified technician in your area. Yearly inspections after the first or second year are a good idea. G&D partners with multiple service companies throughout the country if you need a recommendation.

What is a btu?
British Thermal Unit: The amount of energy needed to cool or heat one pound of water by one degree Fahrenheit.
What does it mean when someone says you need a 5 ton chiller?
A refrigerated ton is a measurement of BTUs, where 1 ton = 12,000 BTU/hr. It is important to know how many BTUs a particular chiller can produce at your required leaving glycol/water temperature.
