DX EVAPORATORS

The new range of EX heat exchangers was designed to cover all three chiller efficiency levels. The medium and low efficiency EXL Series features an updated and improved water side geometry that provides maximum versatility in the positioning of water connections, meeting any customer  requirement for both retrofit and newly designed systems. Furthermore, new modular supports were designed to ensure customers maximum freedom of placement. The new EXH Series of direct  expansion heat exchangers was specifically designed for high efficiency applications, and also features a special configuration for ammonia (NH3) and propane (R290)

Capacities of upto and over 2,000 kW, with 1, 2, 3 or 4 independent cooling circuits. High-efficiency internally grooved heat exchange tubes enabling higher heat transfer coefficients & lower inner tube volumes, which entails less refrigerant and therefore a reduction in size and weight.

  • Water side connections can be vertical, horizontal, or axial (EXL outlet connection only)
  • Improved removable header for optimal refrigerant distribution
  • Removable bundle (on all models of EXL Series) for easy cleaning and maintenance
  • Optimized structure and distance between baffles to ensure low pressure drops, customizable according to the flow rate of secondary fluids and/or customer requirements
  • High product standardization
  • Performance with any refrigerant compatible with copper, stainless steel, titanium, and carbon steel

FLOODED EVAPORATORS

The flooded shell and tube evaporators offer the best technical solutions for air conditioning and refrigeration. A broad range of exchange tubes offers customers maximum flexibility when selecting a product. The shell and tubes are made of special high-performance copper tubes, externally finned and internally grooved, with a low fouling factor. By combining the two effects, of the refrigerant side and water side, it is possible to produce evaporators reduced in size and weight compared to those manufactured with conventional tubes, with the same capacity. All products are built to work with tower water, well water and, on request, sea water.

Capacities of upto and over 1,500 kW, with 2 and 4 water side passes. 1, 3, & 6 water side passes available for special applications. Externally finned and internally grooved heat exchange tubes with a low fouling factor enabling higher heat transfer coefficients and lower inner tube volumes – meaning less refrigerant and therefore a reduction in size and weight.

  • Removeable front and rear headers for easy cleaning and maintenance.
  • All carbon steel shells are sandblasted
  • EPDM Rubber gaskets ensure elevated operating pressures & exceptional aging resistance
  • All exchangers can be supplied with floor brackets & liquid level indicators (optional)
  • Performance with any refrigerant compatible with copper, stainless steel, titanium, & carbon steel
  • Additional liquid receiver available on request

CONDENSERS & DESUPERHEATERS

A broad range featuring 12 exchange tube length geometries offers customers maximum flexibility  when selecting a product. The shell and tubes are made of special high performance copper tubes, externally finned and internally grooved, with a low fouling factor. By combining the two effects, of the refrigerant side and water side, it is possible to produce evaporators reduced in size and weight compared to those manufactured with conventional tubes, with the same capacity.

All products are built to work with tower water, well water and, on request, sea water.

  • Capacity up to over 2,000 kW, with 2, 4, and 8 water side passes
  • 1, 3, and 6 water side passes available for special applications
  • Externally finned and internally grooved heat exchange tubes with a low fouling factor enabling higher heat transfer coefficients and lower inner tube volumes, meaning less refrigerant and therefore a reduction in size and weight
  • Removable front and rear headers for easy cleaning and maintenancec
  • All carbon steel shells are sandblasted
  • EPDM rubber gaskets ensuring elevated operating pressures and exceptional aging resistance
  • All exchangers can be supplied with floor brackets and liquid level indicators (optional)
  • Performance with any refrigerant compatible with copper, stainless steel, titanium & carbon steel

LIQUID RECEIVERS

Liquid receivers are pressure vessels with a cylindrical tank and rounded base plates, supplied with accessories such as liquid level indicators and special fittings.

The ideal solution for storing refrigerant charge to absorb fluctuating system loads. The storage capacity of ERH & ERV liquid receivers ranges approximately between 8 and 2,300 liters. Larger customized solutions are available on request. Receivers are available in two series: ERH horizontal and ERV vertical liquid receivers.

Materials
Standard ERH and ERV liquid receivers are made of carbon steel. Refrigerant side connections are either welded or realized with Rotalock fittings.

Tests, standards, operating limits
All liquid receivers undergo pressure tests according to the parameters and procedures prescribed by the certifications below. The assembly, installation, and permanent connection of components and/or accessories must comply with the standards in force. Since liquid receivers are pressure vessels, their safety requirements are regulated by Pressure Equipment Directive PED 2014/68/EU with regard to mechanical design, material selection and use, production and inspection, pressure testing, and final documentation. The certificates of conformity issued under former directive 97/23/EC are valid under the current directive (Art. 48, par. 3, Directive PED 2014/68/EU).
