Overview of Reznor HVAC Reznor is dedicated to providing effective, value-conscious solutions to your Heating Ventilation and Cooling needs. Reznor 1930s Factory Video This film was taken in the early 1930s to show the "modern" Reznor manufacturing facility. The Reznor PREEVA High Efficiency condensing units SHH and RHH are the latest variants of our compact air handlers.They are capable of providing heating, cooling, ventilation and free cooling, with varied classes of air filtration. The difference with the regular PREEVA air handlers is that the SHH and RHH have a secondary heat exchanger for additional heat extraction out of the flue gases.The indoor (SHH) and outdoor (RHH) installations are suitable for connection to ductwork and the indoor SHH  units can also be used as free blowing units.They are an ideal fit for industrial buildings, commercial and retail premises, warehouses, sports and leisure halls and churches.All units are manufactured by means of factory-assembled modular sections, which allow an easy  selection of possibilities, including air mixing modules , filter modules or cooling modules.

The base frame is also a modular design.

The Reznor brand PREEVA air handling units for heating, ventilation and cooling can be installed indoors or outdoors. An optional cooling coil allows the application of a chiller, condensing unit or even a heat pump. Heat recovery is one of the many other energy saving possibilities. Case Study : Year round comfort for sustainable Quick restaurants Quick is a chain of Belgian fast food restaurants who are currently redesigning their restaurants to become more sustainable, reducing energy use. This concept requires high efficiency heating and air conditioning as well as heat recovery.

It should come as no surprise that Reznor's PREEVA air handling units were selected to give the end user year round heating and cooling comfort at the highest efficiency. Installation – simple and safe Compact all-rounders: The mechanical designs RadiPac stands for ... Installation: Simple and safe The electronics and motor form one unit – this doesn't just save space, but also ensures easy installation. Here, an integrated electronics system for commutation and control replaces an external frequency converter. Because the motor and electronics in the motor system are already perfectly matched to one another, additional electronic filters and shielded cables are not needed. Hence there is no need for any costly component matching on commissioning or for earthing and screening work. The impeller, motor and electronics system are all optimally adjusted to one another, leading to an overall efficiency of well above 60%.A significant contribution to this efficiency is made by the external rotor design GreenTech EC motor.

This is a mains-powered, permanently-energised synchronous motor with electronic commutation (also called BLDC). The construction of other permanent magnet motors of comparable efficiency with internal rotor designs requires the use of these rare-earth magnets. stand up air conditioner cheapThis also results in a loss of compactness and simplicity of assembly and commissioning due to the necessary external control electronics.ac unit diy Only optimised interaction ensures that the whole is more than the sum of its partsair conditioner outdoor unit cost Aerodynamically optimised blade channelIntegrated rotation diffuserInlet nozzle adjusted to impellerLow noise emissions Angular trailing edge for optimised flow controlIntegrated rotation diffuserInlet nozzle adjusted to impellerLow vibration

The performance measurements for all fans are conducted on cutting-edge chamber test rigs. The entire fan unit, consisting of the motor, the control electronics and the impeller, is measured at different load levels. This provides us with reliable data, meaning that when you are choosing your fans, you can count on these values being met. This rules out any nasty surprises when commissioning the fans. The measurement data form the basis for the selection program, which is available on request. This software enables you to calculate operational costs or to conduct a comprehensive cost analysis across the life-cycle.
