CO2 compressor rack systems

eCO2 Technologies have developed a wide range of low pressure (LP) cascade, high pressure (HP) cascade and CO2-only racks based on Dorin CO2 compressors, refer to the table below

eCO Freez

The eCO Freez racks are CO2-only (HFC-free) units, and operate in sub-critical or transcritical mode, depending on ambient conditions. eCO Freez units offer low temperature (LT) cooling only in a capacity range from 10 to 80kW.  Optional interstage heat recovery provides all year round steady hot water, where required.

eCO Cool

The eCO Cool racks are CO2-only (HFC-free) units, and operate in sub-critical or transcritical mode, depending on ambient conditions. eCO Cool units offer medium temperature (MT) cooling only in a capacity range from 20 to 300kW.

eCO Duo

The eCO Duo racks are CO2-only (HFC-free) units, and operate in sub-critical or transcritical mode, depending on ambient conditions. eCO Duo units offer both  LT and MT cooling  in a capacity range from 10 to 80kW (LT) and 20 to 250 kW (MT).  eCO Duo units allow evaporators to be switched betwwen LT and MT with ease, very useful for swing cool/freezer rooms. eCO Duo systems are also the most efficient CO2 racks available.  Low temperature compressors are fitted with the efficiency-boosting ESRS system.  Optional interstage heat recovery provides all year round steady hot water, where required.

eCO Freez Cascade

The eCO Freez Cascade racks require an additional high stage cooling source, such as chilled water, chilled glycol or direct refrigerant, generally at temperatures < +10deg C.  eCO Freez Cascade units offer low temperature (LT) cooling only in a capacity range from 10 to 80kW.  Optional interstage heat recovery provides all year round steady hot water, where required.

eCO Freez LP Cascade

The eCO Freez LP Cascade  require an additional high stage cooling source, such as chilled glycol or direct refrigerant, generally at temperatures < -5 deg C.  eCO Freez LP Cascade units offer low temperature (LT) cooling only in a capacity range from 10 to 80kW, and are a low cost entry into CO2 refrigeration
