Short characteristic:

Fan cooler-heater units LEO COOL is 2 in 1 device that provides cooling in summer and heating in winter.

The devices are designed for indoor use where maximum air dustiness does not exceed 0,3 g/m3. It is an universal device which effectivelly cooperates with thermal sources such as condensing gas boilers, chillers or reversible heat pumps, characterized by low temperature of the heating medium.

The LEO COOL come with 3 step fans withan increased range of regulation of efficiency, cooling capacity (2,2-37,4 kW) and heat power (3,1-65,4 kW).
Two types of fan cooler-heaters are available: with 3-row water heat exchanger or with 4-row water heat exchanger.

More info about comprehensive solutions for heating and ventilation can be found on page FLOWAIR SYSTEM.

Purpose:

Fan cooler-heaters are used for heating industrial halls, mid-size and large facilities for instance logistic centers, production halls, food industry halls, sports halls, warehouses etc.

Control system:

Two control options for LEO COOL units:
- TS control – basic functionality and easy of use,
- T-box regulation – advanced functionality, control by the means of BMS or by T-box intelligent touch-screen controller.

Technology/innovation/benefits:

Condensate drain system - droplet eliminator equipped with outlet blades prevents condensate droplets from escaping with supply air stream.

Air blades – enable to set the direction of the supply air stream,

Heat exchanger – a big heating and cooling capacity is provided thanks to 3-rows or 4-rows water heat exchanger with hydrophilic layers and thin lamellas spacing,

Casing – light and durable, made of EPP (expanded polypropylene),
Rotary console 170° - mounted vertically, ensures easy mounting to the wall
