CO six
Industrial Transcritical CO2

The CO six range is built for industrial refrigeration, from -50°C blast freezers through to +12°C air conditioning applications, using six cylinder piston compressors to offer durable, high capacity cooling.

CO six

CO six offers a huge range from 250 kW right through to 1.2MW and can be manufactured bespoke to ideally match your application needs. This six cylinder range is also compatible with our CO pump transcritical pumped CO2 system.

The CO six capacity can be matched directly to the cooling load with speed controlled lead compressors. In booster configuration, CO six provides dual temperature capability, both freezing and chilling independently and simultaneously.

CO six uses our latest intelligent electronic control techniques, which have been developed and refined over many years. This enables isentra CO2 Compressor Packs to support an outstandingly smooth operation with excellent reliability, constant temperature performance, and optimum energy efficiency.

Built on an impressively strong, fully-welded steel frame, which is powder-coated in a tuff-textured finish to stand the test of time, the main refrigerant vessel is wrapped in wax tape for complete corrosion protection. 

As with all isentra products, internet connectivity and energy monitoring are standard features. isentra systems also come, as standard, with high pressure standstill capability. Our ‘60 bar’ concept works alongside a unique valve shutdown strategy to provide the ultimate in resilience and reliability. A coalescent oil system, fitted with a fully serviceable filtration system is standard too.

All isentra products come with a Two Year Parts Warranty (T&Cs apply), UKCA mark and a declaration of conformity, and are approved by an independent PED (Pressure Equipment Directive) notified body.
