Dometic Marine, the world leading supplier of marine air conditioning, launches the Cruisair® MTD Chiller Series, which has been re-engineered to use R410A environmentally safe refrigerant. Fully compliant with International green gas standards, the thermodynamic properties of R410A enabled Dometic engineers to increase efficiency by using fewer amps per capacity.
The nine-model MTD Chiller Series ranges from 24,000 to 120,000 BTU/hr (2-10 tons) capacity. Its compact, modular design will appeal to builders and designers seeking more efficient use of on-board spaces. In line with other air conditioning units from Dometic, the Cruisair® MTD provides maximum performance and reliability coupled with flexible installation and ease of maintenance.
The Cruisair® MTD series has been designed to appeal to the widest range of builder specifications. To achieve capacities beyond 120,000 BTU/hr, multiple modules can be utilised; custom frame and water-manifold installations are also available for multiple-module use. Each model is available with a range of compressors to suit a variety of power systems. Each unit has two sub-modules that can be separated for remote mounting and rotated to achieve more convenient water-connection locations or compressor access.
The Cruisair® MTD series is a tempered water reverse-cycle unit that both heats and cools. Thermal expansion valves optimise performance over a wide range of conditions, while a hot-gas bypass valve maintains heating performance in cold seawater and helps prevent water freezing in the heat exchanger. The unit's ability to heat in seawater temperatures as low as 3.5°C (38°F) removes the need for a separate fossil-fuel or electric water heater in most applications.
The Cruisair® MTD comes with a scroll compressor as standard and faster condensate drainage is achieved with the inclusion of larger drain fittings. The seawater headers are connected to condensers via flexible hose to improve alignment for customer connections and added strength is provided by reinforced stainless-steel seawater connections. For ease of maintenance, the seawater manifolds are removable to allow cleaning of the condenser tubing.
Start-up power surges can be eliminated through the addition of an optional Variable Frequency Drive (VFD), which will also run the unit at full capacity 60Hz even with a 50Hz input.
Dometic Marine will launch its extensive range of new products at the Miami International Boat Show, 11th - 15th February 2010. For further information please visit the team at Booths Q61, Q65 and Q71 in the Convention Center.
