Hycool® Heat Transfer Fluids

Hycool's Excellent Environmental Profile

A compatible combination of Hycool® LT heat transfer fluids, George Fischer Cool-fit pipework, operated by Frigadon Chillers in conjunction with 12 AIA Coils.

Hycool® Consists of potassium formate and de-ionised water and is the preferred coolant for process cooling, freezing, cooling and heating applications.

Hycool® Has outstanding thermodynamic properties minimising both capital and operational costs.

Hycool® Has low viscosity and high thermal conductivity. Combined they result in reduced installation and energy usage costs.

Hycool® Has excellent environmental properties. It is non-toxic, non-flammable, is biodegradable and chemically stable.

A Secondary Heat Transfer Fluid

• It should be non-toxic, even in larger quantities.
• It should be environmentally friendly.
• It should be biodegradable.
• It should have excellent thermodynamic properties.
• It should be capable of achieving as high COP as possible.
• It should have low corrosion effect.
• HYCOOL® fulfils all the above statements.

What is Hycool®?

HYCOOL® is a secondary refrigerant based on potassium formate. Potassium formate is an organic salt. Chemical formula HCOOK.

HYCOOL® has a high environmental profile.
Safe to handle, non-toxic and biodegradable.

HYCOOL® has excellent thermodynamic properties and with its low viscosity and high thermal conductivity will ensure minimal energy consumption. It should be environmentally friendly.

Glycol vs Hycool® vs Water

With the same volume of fluid in each test tube egg timer, water demonstrates the most rapid flow rate but only at a temperature no colder than 0° C. Propylene glycol with its high viscosity but restricted heat transfer temperatures no lower than -8° C shows a much slower rate compared with HYCOOL®

Conclusion:

HYCOOL® heat transfer fluid with the lower viscosity compared with glycol will reduce the energy costs by 12% to 15% to transport heat/cold/energy to achieve the same results

Free Heat: Heat Recovery Energy Savings with SRS installations

Secondary Refrigerant Systems can provide ‘free heat’ for under floor heating systems.

• Are designed to provide radiant heating by means of pumping warm heat transfer fluid or water generated by the ‘SRS’ (Secondary Refrigerant System) for Supermarket or cold store warehouse installations.
• Are clean and create low velocity air convection, thus reducing dust particle levels and provides a warm and comfortable environment for customers and store operatives alike. No fans, no noise, no dust and no maintenance.
• Use reclaimed heat from the Secondary Refrigerant System thus harnessing ‘free heat’ waste energy from high and low temperature refrigeration systems. In summer this is diverted through a SRS dry cooler.

Hycool® Heatwave

• ‘Heatwave’ under floor heating system is designed to provide under floor radiant heating by means of pumping warm heat transfer fluid or water generated by the ‘SRS’ (Secondary Refrigerant System) for Supermarket or cold store warehouse installations.
• It is clean and creates low velocity air convection, thus reducing dust particle levels and provides a warm and comfortable environment for customers and store operatives alike.
• It uses reclaimed heat from the ‘SRS’ System harnessing waste energy from high and low temperature systems which in summer this is diverted through a SRS-AIA dry cooler.
• As hot air rises it makes sense to use under floor convection heating as oppose to using a more traditional method of overhead heating which requires fans and more power. Fans use energy and create draught and dust.
• Can be installed for the supermarket sales floor providing heat between refrigerated display case aisles but similarly for the goods-in and external walkways.
• The success of such installations in Sweden using this method of “free heat” reclamation generated from a SRS (Secondary Refrigerant System) installation ensures an environmentally friendly and the best long term cost effective option.
