Product Introduction

The 4 hp physical build produces 7.80 kW at the same referenced low-temperature condition as the smaller unit. Increased compressor displacement and condenser area suit medium pharmaceutical, test or controlled-food storage systems using a remote evaporator.

Key Features

Medium refrigeration output

The larger compressor matches evaporators that exceed the practical duty of the 2 hp package.

Greater air-side capacity

The enlarged coil and fan arrangement remove the additional compressor heat at outdoor conditions.

Service-ready circuit

Packaged refrigerant controls consolidate the compressor and condenser components outside the served space.

Medium process refrigeration, pharmaceutical controlled storage, test chambers and clean-support cold rooms.

Solutions for Your Application

The compact 4.3 kW unit cannot pull down the medium cold-room load.Use the 7.80 kW compressor and condenser build after checking the evaporating and ambient design points.

Hot discharge air may recirculate around a larger condenser face.Maintain free intake and discharge clearances and avoid enclosed plant niches.

Available Options

Receiver sizing, fan-speed control, winter kit, pressure switches, service valves, acoustic treatment and remote status contacts are available.
