LREQ-BY1

ZEAS condensing unit for

commercial refrigeration
with scroll technology

Refrigeration solution for medium to large capacity
applications featuring proven VRV technology

› One model for all applications from -45°C to 10°C evaporating
temperature
› Perfect solution for all cooling and freezing applications with
variable load conditions and high energy efficiency requirements.
In particular used in supermarkets, cold storage, blast coolers and
freezers etc.
› DC inverter scroll compressor with economiser function results in
high energy efficiency and reliable performance
› Reduced CO2 emissions thanks to the use of R-410A refrigerant LREQ-BY1(R)
and low energy consumption
› Factory tested and pre-programmed for quick and easy installation and commissioning
› VRV (Variable Refrigerant Volume) technology for flexible application range
› Increased installation flexibility thanks to limited dimensions
› Low sound level including „night mode“ operation
› For small freezing capacity, single ZEAS units can be connected to a booster unit
› Dedicated unit to allow multi combination of 2 x 15 HP or 2 x 20 HP resulting in less pipework or installation time
