Standard Features

Insulated Panels

The frame is constructed of 16 gauge steel sheet metal for maximum strength. All exterior panels and corner posts on the frame are powder coated for durability and an attractive finish. The side panels are double wall construction (inner and outer panels) with insulation between. The insulation is 12 mm (1/2 in) thick fiberglass. The walls isolate the insulation from the air stream and further reduce sound levels. Panels are hinged and removable for easy access. The cabinet is serviceable from the front of the unit.

Electronically Commutated (EC) Fans

Each unit is equipped with electronically commutated (EC) fan modules. This technology increases fan efficiency by up to 30% while reducing operating costs. Each fan module has an anti-vibration mounting to isolate it from the unit structure.

Electrical Panel

The electrical panel contains the contactors, starters, overload protection devices, and input power disconnects.

Main Power Disconnect Switch

A main power disconnect switch disconnects all high voltage power to the unit if necessary. The disconnect switch is accessible without removing the electric box cover.

Network Management Card

Permits multi-level access to monitoring, control, and event notification features over the building management network.

Refrigeration System and Compressor

The refrigeration system operates under a master controller for greater efficiency and accuracy. Suction and discharge pressures (DX models) are monitored and electronically controlled. The scroll compressors are designed for year-round operation with a 15-year life expectancy. The controller microprocessor provides real-time suction and discharge pressure readings reported by transducers installed on the refrigeration system.

For compressor protection, the InRoom precision air conditioner utilizes charge isolation and crank case heaters during off cycles (DX only). This eliminates the threat of liquid refrigerant migration that could lead to compressor slugging and lubrication issues.

Mains Automatic Transfer Switches

Mains automatic transfer switches allow two power sources to be connected to the cooling unit. A secondary power source (generator or UPS) can be automatically transferred in the event of a failure of the main power source to maintain cooling. Programmable switches are voltage adjustable with On and Off delay which can be adjusted from 0 to 20 seconds. The Off delay should be set to 3 seconds. Contact customer support for assistance to determine your requirements.

Duct Flange

A 25 mm (1 in) duct flange is included for the upflow units to provide convenient connection to external ductwork for either supply or return air as needed.

Evaporative Freeze

Protection

Suction pressure is actively monitored by two individual sensors and controlled by the microprocessor controller to calculate the opening of the electronic expansion valve, eliminating the risk of condensate freeze-up on the evaporator coil.

Redundant Group Control

Allows up to 16 units to communicate with each other for redundancy, demand fighting prevention, and mode assist. Global sharing of certain settings requires a twisted pair shielded wiring interconnection.

30% ASHRAE 52.1 Filters

The filtration of conditioned air is extremely vital to maintaining the clean, particle-free environment required by electrical equipment. The system uses 30% (100 micron) filters, with full depth filter pleats. Deeper filters produce a lower pressure drop, requiring less energy during normal operation. Filters are replaceable through the front of the upflow unit and through the top of the downflow unit.

Condenser (Direct Expansion units only)

Standard air cooled condensers are suitable for cooling up to the maximum ambient temperature of either 35°C (95°F) or 46.1°C (115°F) depending on the requirement. These condensers have variable fan speed controls to allow operation down to -28.9°C (-20°F).
