Up to now, OSB heat pump manufacturers have signed distribution sales contract with more than 3 different countries!
How could OSB’s product can attract qualified customers from all over the world and willing to sign distribution sales contract with OSB?
Since you are already here, you may have known that OSB have been in this industrial field for 20 years since 1999. Backed with the rich experience for air conditioning, seizing the market demand of industrial heat pump products, OSB have been evolved many times for the past 20 years.
Just to take swimming pool heat pump as example, we have 2 to 90kw different heating capacity models, with various experiences in steel cabinet, plastic cabinet, stainless steel cabinet, with different design!
Not only with the outside look of the heat pump but also the internal design also has been adapted or modified based on different customers’ requirement.
As you may or may not know, one of the important components in a pool heat pump is EEV.
EEV shorts of Electronic Expansion Valve.
The EEV is basically composed of a read valve, an orifice and an electric coil. At certain time intervals, voltage is applied to the coil of the valve actuator, causing current to flow in the coil and creating a magnetic field that opens the valve.
An there is another option that is “CT”, which can also be used as the same role as EEV.
CT means Capillary tube, it has no moving parts, nothing to war out, and is simple and inexpensive.
It allows the pressures in the system to equalize during the off cycle, thus reducing the compressor starting torque requirements. On the other hand, the capillary tube can not be adjusted according to the changing load of conditions and requires the refrigerant charge to be held within lose limits.
And “TXV”, Thermostatic expansion valves also been used in OSB ‘s pool heat pump. TXVs are one of the most common type of adjustable orifice throttling device in the air conditioning and refrigeration system worldwide. They earned this place by being both efficient and affordable.
And of course, different choice of the throttling device would also affect the price to some degree, you may verify with your suppliers and select the right one you need!
