New S727 dual circuit evaporator
The new Onda Brazed Plate S727 is the larger plate in the BHE portfolio and it has been developed to respond to Air Conditioning and
Process Cooling applications with low pressure refrigerants as R1234ze, R515B, R513A and R134a.
The design of the plate corrugation pattern has been optimized thanks to a CFD analysis supported by thermal laboratory test.
New patented distribution system which allows to achieve stable performance with large plate package reaching a cooling capacity up to 700 kW .

Introducing Onda
Onda’s main industrial segments are in HVAC&R. Onda is one of the market leaders, thanks to its high know-how, and the fact that Onda S.p.A. is a supplier of the major OEMs.
Onda has four production plants, two located in Mussolente, one in Lonigo and one in USA (Delaware, OH). In the Lonigo plant approximately 9,000 square meters are used for the manufacturing of shell and tube heat exchangers and air heat exchangers. The plants in Mussolenteare dedicated to the production of brazed plate and plate and frame heat exchangers and to the manufacture of large industrial vessels as well as mechanical machining.
The manufacturing plants include a total area of approximately 23,000 square meters. In addition, all Onda plants are certified according to EN ISO 9001:2015. The professionality and detailed knowledge of pressure vessels rules allow Onda to receive any request of compliance with international standards, and to supply special and customized products.

Coils
The commercial HVAC system has a variety of components. Each of these works together to ensure overall system performance. If any of the components breaks down, then the whole system will not be far behind. However, just one part gets most of the attention.
As you can probably guess, that part is the compressor.
It’s true the compressor is the “heart” of the HVAC and does the most work. However, we caution you to remember many system problems don’t originate in the compressor. When you suffer early compressor failure, it often means there is another problem that has gone unnoticed.
The condenser is the heat exchanger that serves as the hot side of the air conditioning unit. It removes heat from the building and transfers it to the exterior. Gas refrigerant then becomes liquid refrigerant. A heat pump can also have a condenser, in which case it functions to collect heat from the outside.
The air handler which includes the evaporator coil and the blower, is the component responsible for circulating air through the system. In most structures, it is connected directly to the ductwork. It blows cooled or heated air into the building and then returns it back into the system. It includes a blower, heating and cooling elements, and a variety of other devices.
Of all the different parts of the air handler, the evaporator coil is the one most likely to need maintenance or replacement. The evaporator coil holds chilled refrigerant received from the compressor. As air from the blower fan moves over the coil, heat is removed from the air in the treated area.
