standards and variants of APTE high performance heatexchangers

APTE^® Apparatetechnik Harald Schönstein GmbH

The types
WP	the standardrange of our products; all special models available.
WP-E	Economy types. The max. operating pressure ia 16 bar. Solder Copper.
TD	two evaporators or condensers in a device, consisting of two independent refrigerant circulations and one sole circulation. The flow of the refrigerants is carried out in the diagonal current principle for an optimal usage of the heat transfer area. The TD 07 guarantees the full performance for one of the two evaporators or condensers even if you shut off the other refrigerant circuit. Solder: Copper.
NP	solder is Nickel. The use of nickel brazed heatexchangers can become necessary where agents such as i.e. deionisized water, ammonia is used.
NP-HP	Series of nickelbrazed heat exchangers supported by a pressure frame has been developed for applications which requires a max. operating pressure of 27 bar. Available for modeltypes 05 and 07.
AE	are exclusively used as evaporator. The distribution system for the refrigerant is incorporated in the refrigerant inlet of the heatexchanger. The distibutionsystem is made out of stainless steel and provides precise metering of the refrigerant to the channels. Solder Copper or Nickel.
XCR	the plates consist of a high grade corrosion resistant stainless steel, named SMO 254 [AISI S31254]. The XCR series has been developed for special applications, such as pool heating, ground water heat pumps etc. Solder Copper or Nickel.
DW	DoubleWall. This system consists of two stainless stell plates instead of one to seperate the two heatexchanger chanels. In case of unlikely internal damage, due to e.g. pressure pulses, the change of fluid contamination is reduced. Solder Copper.
WG	these units have a wider gap between the heatexchanger plates, designed for low pressure drop application with viscous fluids. Solder Copper or Nickel.
