Ecosaire® Features

TOTAL PROTECTION — THE ECOSAIRE® APPROACH

Ecosaire® has been maintaining optimum operating conditions in data centers throughout the world for more than three decades.

Recognizing the emerging trends toward smaller, more powerful hardware with reducedcooling requirements, Ecosaire® designed the CM Series of three, five and seven-ton cooling unitswith features specifically aimed at providing increased reliability, serviceability, and energyefficiency.

Heavy-duty Scroll compressors, all-copper refrigeration tubing, state-of-the-art microprocessorcontrols, heavy-duty electrical components, and the Humitronic canister humidifier all contribute toexceptional durability. Separate circuit breakers protect the compressor, fan, humidifier, and electricreheat so there are no troublesome fuses to replace. The CM Series units provide year-round service,twenty-four hours a day, 365-days a year.

Computer rooms are kept at comparatively high humidity conditions to prevent staticelectricity problems. Most air conditioners remove this humidity as a normal function of the cooling process, forcing their humidifier to make up the loss. Since an electric humidifier can bevery expensive to operate, Ecosaire® has designed the CM Series so it does not remove excessivehumidity during normal operation. By providing high sensible cooling, compressor energy is notwasted on unnecessary dehumidification so the humidifier does not have to work overtime.

By providing high sensible cooling, compressor energy is not wasted on unnecessarydehumidification so the humidifier does not have to work overtime.

Few business situations require more immediate attention than a data center that has beenshut down. Should a problem arise with the CM Series, it can be serviced with exceptional ease.Readily accessible compressors, fan assemblies, and electrical components assure quick repair. Each belt-driven fan assembly employs a blower motor set for fast changeouts. Total side serviceprovides easy access to the air filters and components.

ALL UNITS FEATURE:

• High sensible cooling• Small footprint• Microprocessor controls• Non-locking disconnect switch• Individual branch circuit breakers• Thermal/acoustical insulation on all interior cabinet surfaces • Two pleated filters• Crankcase heater• Refrigerant reclaim valve• Automatic restart after power failure• Horizontal discharge• Quick changeout blower assemblies• Belt-driven blowers• ETL Listed

STANDARD FEATURES

The Supervisaire® Microprocessor Controls provide extremely user-friendly, programmablemonitoring and control for all Ecosaire® Precision Environment Control systems. Individual Ecosaire®units can be connected to a built-in local area network together with a supervisory panel completewith a backlit graphics display for robust redundant environmental control. At the same time, thesystem can be connected to a personal computer supervisory system either directly or via a network,or to a BACNET™, ECHELON™ and MODBUS™ interface.

A wall-mounted remote control panel with display is standard, and can be mounted in a convenientlocation.

Efficient motors power each belt-driven blower. Each blower assembly is accessible through the side of the unit and allows the blower to be removed and replaced quickly should the need arise. Each blower motor is two-speed to allow even air flow over the entire coil while the unit isdehumidifying with reduced air flow. On down flow units, a vertical air discharge plenum helpsreduce back pressure for maximum air flow and efficiency.

The refrigeration system consists of a high-efficiency Scroll compressor, filter/dryer, low-pressure switch, manual-reset high-pressure switch, externally-equalized thermal-expansion valve,sight glass/moisture indicator, refrigerant reclaim valve and refrigeration service valves.

The compressor is located behind an access panel for ease of service while in operation. Coppercooling coils and refrigeration tubing are used throughout. The cooling coil includes a corrosion-resistant stainless steel drain pan.

Ecosaire® has given careful consideration to all the needs of the serviceman. We made sure thateach component could be serviced or replaced without interference from other parts or from theunit itself. All refrigeration and humidifier components are easily accessible. Electrical componentsare conveniently located at the front of the unit and are positioned for easy changeout. The filterscan be replaced from the side. Easy side service access also means zero clearance requirements onboth ends of the unit, allowing installation in tight places.

A factory mounted non-locking disconnect switch is standard on all CM Series units,eliminating the need for a field supplied, wall-mounted disconnect.

All CM Series equipment are warranted to be free from defects in material and workmanshipfor a period of one year.

FACTORY-INSTALLED OPTIONS

The Humitronic® steam canister provides 100 percent particle-free steam to the computer roomwhich is essential to computer reliability. Steam canisters operate with greater efficiency and lessmaintenance than any infrared or immersion humidifier available. The humidifier can be adjusteddown to 20 percent of rated capacity to match room load conditions.

Steam is generated by passing an electric current through ordinary tap water in a non-conductivecylinder. The water quickly reaches boiling temperature, producing pure steam. No other form ofhumidification is as clean.

Installation is simple. No expensive water treatment is required. A simple 6.35 mm (1/4”) copperor cold-water supply tube is all that is needed.

Service requirements are reduced to a minimum. When the plastic cylinder is filled withcontaminants, the cylinder is simply discarded and quickly replaced.

Enclosed, low-watt density, fin-tube electric heating elements are available to maintain roomtemperature requirements. They are designed to withstand moist conditions and feature optional 2, 3 stage or proportional control.

A hot-gas reheat coil can be furnished complete with three-way hot-gas valve and arefrigerant check valve. The coil is constructed of copper tubes expanded into aluminum fins. The hot-gas reheat coil maintains room temperature during the dehumidification cycle only.

A hot-water coil can be furnished to maintain room temperature. The coil is complete withtwo-way valve and Y-strainer. The coil is constructed of copper tubes expanded into aluminum fins.

Supervisaire® Microprocessor Controls provide easy-to-use, programmable monitoring andcontrol for each unit. Precision control is enhanced by presenting the user with current roomconditions, set-point control, system operational status, password protection, screen scrolling,menu-driven displays, alarm history and more.

For colder climates, the air-cooled condenser can be provided with a factory-installed three-way head-pressure control valve, a check valve, and an insulated, heated liquid receiver sized to provide –40°C (–40°F) low-ambient operation.

A factory-mounted combination fire and smoke detector is available to activate the unit’salarm and to shut down the unit.
