OHA RHE “Radiant High Efficiency” is a technologically innovative gas combustion unit for heating large spaces.
The OHA RHE radiant strip system provides uniform heat throughout the entire radiant circuit, thanks to its continuous heat output modulation, heating the environment uniformly to achieve maximum efficiency. The circuit functions are optimised through the respective control systems, which allow heating to be managed in thermal zones.

HOW DOES IT WORK?

A microprocessor calculates the power capacity of the motor needed by OHA RHE burner, in order to deliver the correct power able to satisfy the real thermal requirements of the building to be heated. The inverter, included in the OHA RHE burner, modulates the electrical consumption of the fan, keeping the temperatures of the fumes constant and eliminating the overshooting. Thanks to the climatic regulation of OHA RHE , the temperature of the fumes flows more smoothly. In this way the power excesses, which cause continuous ignitions and shutdowns of the burner (overshooting effect), are avoided and the consumptions are strongly reduced.

Homogeneous heat = Max performance

PRE-ASSEMBLED MODULES

Pre-assembled radiant strips are complete and ready for use, allowing considerable reduction in installation/removal times, thus limiting installation costs as well as costs for disposal of packaging.

TUBE JOINTS

The joints connecting the radiant tubes have been designed for easy sealed connection of the tubes, with no need for silicone or additional adhesives.

ADVANTAGES

• A noticeable reduction in electricity and gas consumptions
• An optimal combustion efficiency, regardless of the length and configuration of the radiant circuit.
• OHA RHE technology allows to uniform the heat along the whole radiant circuit, heating homogeneously the environment.
• High noiselessness of the burner (according to DIN-VDE-0530 standards)
• More flexibility of application: OHA radiant strips are suitable to heat buildings with particular shape, thanks to the ducts that can be joined and fitted to any architectural geometry.
