LEO COOL cooler and heater is a versatile device that creates a decentralised cooling/heating system. Thanks to its design, the LEO COOL cooler and heater allows you to adjust the capacity and direction of the air, which ensures effective and even distribution of cool or warm air in the room.
The unit is equipped with a high-performance axial fan, which ensures high airflow while keeping noise levels low. Three power versions (3, 5 and 7 kW) are available, so you can choose the right cooler and heater for the size of the room. LEO COOL water cooler and heater is a 2-in-1 device. It provides cooling in summer and heating in winter. The device works effectively with ecological, low-temperature heat sources, such as condensing gas boilers, chillers, or reversible heat pumps.
By equipping them with the DRV control module, it allows them to be connected to the intelligent FLOWAIR SYSTEM. Centrally controlled devices know exactly when to operate, which results in a variety of savings. The T-box controller with touchscreen display, which is the brain of the SYSTEM, also controls all devices from one place.

A simple and reliable solution for year-round facility operations. The special design of the device provides high heating and cooling power.
A condenser equipped with air blades prevents condensate droplets from escaping with the supply air stream. Condensate is drained by gravity from the condensate drain pan (a condensate drainage hose should be connected to the pan).
Adjustable horizontal air blades make it possible to direct the airflow according to individual needs.
The LEO COOL cooler and heater is fitted as standard with an energy-efficient fan with a 3-speed motor. To najprostszy i efektywny sposób na sterowanie pracą nagrzewnicy.
Cooperation with heat pump
The LEO COOL unit is equipped as standard with high-efficiency heat exchangers that guarantee comfort in the hall even when working with low-temperature heat sources. Advanced control ensures service-free interoperability with heat pumps. An additional advantage of the solution is the use of water or glycol solution as a medium for heating or cooling, which guarantees greater safety and lower environmental impact.
Application
LEO COOL water cooler and heater is used for cooling or heating of objects with large cubic capacity of general and industrial construction, public buildings, such as sports halls, or halls of food industry. They are designed for indoor operation with a maximum air dustiness of 0.3 g/m3.
