Chiller Compact

FEATURES ---------------
Innovative Modular Design
  • Compact base design and footprint allows flexibility in space, usage and layouts.
  • Individual modules can be multiplexed to provide precise capacity requirements for any application.
High Efficiency Components
  • Thermodynamically matched components assure maximum performance.
  • Tecumseh Rotary and Copeland Scroll compressors provide high efficiency performance with less power consumption and quieter operation. The cylindrical shaped compressor allows for a compact encased design.
  • Fewer moving parts ensure higher reliability.
  • Condenser coil is custom fabricated of spiral fluted cupronickel to provide maximum heat transfer and high corrosion resistance.
  • Exclusive Digital Diagnostic Controller monitors and protects the system through the use of aqua stats, high pressure switches, timers, freeze controls and high limit switches, timers freeze control and high limit switches, all programmed to read out an LED panel for immediate diagnosis.
Quality Assurance
  • Each unit is evaluated to 500 microns, pre-charged, hermetically sealed, load tested and electronically calibrated at the factory.
  • Charge Guard protection provides sealed access ports, ensuring environmental protection and chiller module integrity with no refrigerant in living quarters.
  • All units meet or exceed applicable ABYC and U.S. Coast Guard regulations, CE Directives and general Air Conditioning and Refrigeration Industry (ARI) standards.
Advantages of M.A.S. Chilled Water System vs. Direct Expansion Spilt System
  • No refrigeration line sets and mechanical flare fittings which are subject to leaking refrigerant over time - thus eliminating refrigerant repair within living quarters.
  • Environmentally friendly as hermetically sealed modules.
  • No EPA certified technician required for startup or field installation.
  • Flexible hose is easier to install and insulate compared to semi rigid cooper refrigerant line sets.
  • Provide full cooling capacity to areas which require fast pull downs from hot starts.
  • Most applications result in fewer number of compressors which increases reliability, reduces weight and conserves power.
  • Multiplexed chiller installations typically realize a 50% power savings over 24 hour period.

*Model number breakdown: CHC= Chiller Compact; 16, 20, 24 = BTU/H x 1000; RC = Reverse Cycle; Z = 230VAC; S = Scroll Compressor (Rotary compressors are used on the 16 & 20).
**Standard models operate at 60Hz and 50Hz. However, there is a 17% reduction in capability when operating at 50Hz. Full capacity 50Hz only units are available upon request (220/240V only).
***Add 1.0/2.5cm for each mounting bracket. The four brackets supplied can be mounted on any side of base pan (depth or width).
Installation Guidelines for Chiller Compact
When choosing the proper model CHC Chiller Compact condensing unit, primary consideration should be given to calculate BTU loads and available power supply. The location of the Chiller Compact condensing unit should be dry and accessible for service typically in engine room, lazarette or machinery compartment. Secure the condensing unit to a level horizontal surface with the supplied brackets. These brackets are designed to hold the weight of the equipment as well as handle any torsional movement. Do not stack units directly on top of each condensing unit must be independently supported. Racking is available to facilitate custom installations. Reinforced marine grade hose is to be used for ht seawater circuit. The hose has to be routed upwards from the thru-hull intake to the condensing unit to prevent air locks in the centrifugal seawater pump. Circulation connections between the condensing unit and the chilled water lines are to be made with properly sized fittings and reinforced marine grade hose. All hose connections are to be double clamped and ball valves should be installed at chilled water inlet/outlet of each CHC unit and each air handler for ease of serviceability of the system. Insulate all hose and fittings air tight upon completion of leak tests to prevent condensation and capacity loss. The condensing unit chassis has an integral condensation drain pan for removal of any water that may form. Secure a hose to this drain pan spud and route it downward to a proper sump or overboard discharge outlet. Never install the air handlers in bilge or engine room areas and insure that the selected location is sealed from direct access to bilge and/or engine room vapors. Do not terminate condensate drain lines within four (4) feet of any outlet of engine or generator, nor in the bilge (vapors can travel up the drain line), unless the drain is connected properly to a sealed condensate or shower sump pump. Failure to comply may allow bilge or engine room vapors to mix with the air conditioners return air and contaminate the living areas. All circuit breakers and wire gauge must be sized according to marine design standards. Only stranded tinned copper wire should be used. Route all wiring through the strain-relief connectors provided in the electrical boxes. All equipment should be properly grounded using the grounding lug provided on each unit's chassis. Electrical boxes pre-wired for power with solid state control circuits. The system control switch can either be mounted on the module or remote on a panel for convenient access. All chilled water condensing units use closed-refrigerant circuits, pre-charged with R-22. No additional refrigerant during the installation or at initial start-up and operation of the system. Refer to other individual component sheets for specifications and details of air handlers, controls and related parts. In keeping with regulations set forth by the EPA, only certified technicians should perform service on, or make adjustments to, any refrigerant circuits. However, this is not necessary when installing Chiller Compact.
