GalxC supplies and always recommend the use of blended chiller glycol, which we can have developed especially for chiller systems. Help protect your valuable equipment from the effects of cold weather.
 

Our highly versatile glycol antifreeze is non-toxic, can be used for any process cooling application, including food and beverage installations, as well as HVAC air and gound sourced heat pumps. Proven to significantly lower a fluid’s freezing point. As well as protecting against bacterial growth, inhibit scale and multi-metal galvanic issues, fully blended glycol antifreeze properties are also required in the system as a protection against the elements when a unit is located outside and critical if there is the potential risk of ambient temperature dropping below the 0°C freezing point at any time. This is still a requirement even when the operating temperature of the equipment is running above 5°C.
