MPG Mono Propylene Glycol – Concentrate Heat Transfer Fluids

A FOOD GRADE SECONDARY REFRIGERANT

A major application of heat transfer fluids is their role as secondary refrigerants. Secondary refrigerants like Mono Propylene Glycol (MPG) are used in the refrigeration industry to minimise the quantity of primary refrigerant required to meet the systems cooling requirements. The primary refrigerant is usually expensive, a synthetic greenhouse gas or it can sometimes be a very hazardous product for the operator to handle (e.g. Ammonia or hydrocarbons). A secondary loop is therefore used to transfer the cool from the primary refrigeration unit around the system using a product with good heat transfer properties, that protects the system from corrosion and is non-hazardous for the operator and the public.

A-Gas MPG Concentrate is compatible with most other Mono

Propylene Glycol based heat transfer fluids, but exclusive use of the A-Gas MPG

Concentrate is recommended to maximise the corrosion protection of the system.

MPG Concentrate is available from A-Gas in a 5kg Bottle, 20kg Pail or 215kg Drum.
