Wall/ceiling unit coolers

Features

Advantages

  • Robust design
  • Suction fans, wide air throw
  • Large variety of types
  • Many design types

Easy to Install

  • Ceiling mounting brackets for easy installation
  • Empty tube for defrost sensor
  • Side cover with hinges and quick-release fastener
  • Schrader valve on outlet

Inspection and Cleaning

  • Hinged tray

HACCP Hygiene Certificate

  • Suitable for rooms used for food processing
  • All materials used approved for foodstuffs
  • Drip tray with edges inclined at 45° angle
  • Easy to clean

High Operational Reliability and Leak-Safety

  • Proven Güntner floating coil principle (refrigerantcarrying tubes do not make contact with the casing;increases the heat exchanger’s service life)

Technical details

Heat Exchanger

  • Aligned or staggered tube pattern
  • Special copper tubes for HFC, coolant and CO2
  • Stainless steel tubes for NH3 or steel, hot-dip galvanised
  • Surface-corrugated aluminium fins for high heat transfer

Casing

  • Separate drip plate
  • Corrosion-resistant aluminium alloy AlMg
  • Powder-coated with RAL 9003
  • Large condensation drain with 45° incline

Fans

  • Proven quality fans
  • Standard with two speeds (for fan diameter of 500 mm)
  • Motor protection with thermocontacts
  • 230 V, 1~, 50 Hz or 60 Hz (up to construction size 450)
  • 400 V, 3~, 50 Hz or 60 Hz
  • Wired on connection socket in factory (GHF)

Precise cooling: Fish production in Vietnam

Precise cooling: Fish production in Vietnam

The new fish factory of Hung Vuong Ben Tre produces frozen food in line with HACCP directives for the European and Russian market every day. About 1,500 employees process approx. 250 tonnes of seafood per day on a total area of 30,000 m². Güntner evaporators, air coolers and coils reliably provide normal-temperature and low-temperature storage rooms and freezers with cold. A thermowave plate heat exchanger is used here to connect the primary with the secondary circuit.
