Refrigeration products for any industrial applications and requirements

EFFICIENT COLD


Dual discharge unit coolers

The evaporators manufactured by FRIMETAL are designed to satisfy all the requirements of today´s refrigeration market.

Ceiling mounted evaporators with dual air discharge and low height, designed to be placed in the centre of the cold room ceiling providing a gentle and uniform air flow and making the best use of the space. Valid for the preservation of fresh or frozen products and ideal for aisles or working rooms.

With axial fan motors of external rotor, single phase and diameter of 300 and 400mm in normal version N and silent version S for applications where low level noise or smooth air flow is required.

Dual discharge evaporators designed for use in fast cooling tunnels of medium or low temperatures where high air pressure is required, together with perfect air distribution through the product located on the pallets.

The evaporator must be placed in the centre of the tunnel ceiling and must occupy the entire length of the tunnel. The pallets holding the product must be located lengthways on both sides, separated by a central aisle for the air returning to the fans.
