air to water heat exchangerAir to Water Heat Exchangers

Valutech supplies air to water heat exchangers for a broad range of domestic heating and cooling applications. These air to water units are ideal for heating water in residential and public buildings. Compact and lightweight, these units are designed to maximize heat transfer by utilizing a series of 3/8" copper tubes with a high density of aluminum fins. These fins are spaced in such a way that the fin density is an impressive 12 fins per inch. This unique design allows for heating loads of 50,000 to 60,000 Btu per square foot (please see performance chart below). And though the fin density is high in these air to water heat exchangers, the flow resistance through the coils is surprisingly low.

Applications

  • Residential Heating and Cooling
  • Apartment Buildings and Condominiums
  • Hybrid Systems
  • Air Conditioning
  • Dehumidification
  • Inverter Cooling
  • Solar Heat Dumps

Features of the Air to Water Heat Exchanger:

Materials Tube Coil 36" Seamless Copper
- Plate Fin Aluminum
- Core Housing Galvanized Steel
- Header Copper
Rating: Tubeside 175 psig/350F
Plate Fin Spacing 12/inch -
All Connections 1" ID Solder -

steam Features of the Air to Water Heat Exchanger:

  • Tube Coil is manufactured entirely of 3/8" seamless copper.
  • Plate Fin is made from Aluminum.
  • The core housing is made from galvanized steel.
  • Header is made from Copper and has a 1" ID.
  • The Tubeside is rated at 175 psig/350F.
  • Plate Fin Spacing is 12 per inch.
  • All connections are 1 inch ID Solder and can come with an optional flange and NPT
  • Units kept in stock for immediate delivery.
