Tunnels series A – high capacity tunnels from 4300 to 10600 kg/h for green peas or 3000 to 7500 kg/h for strawberries.
Ammonia NH3 (R717) is the main refrigerant or freon in case of smaller tunnels.
In this series of tunnels we installed centrifugal fans, which significantly improve the quality of fluidization. Tunnels can be additionally equipped with UDS (Equipment for continuous removing frost from the evaporators), which significantly extends the operating cycle of the tunnel between defrostings.
As standard execution you will find pulsator, which supports fluidisation effect and improves quality of frozen product (IQF) and also external system of washing the first belt.
Washing system of the first belt can be activated by operator at any time. System can operate periodically or in automatic cycle.
