FEMA HVAC REQUIREMENTS

1.0 Introduction

This Statement of Work describes the requirements necessary for the purchase, installation and delivery of a HVAC Mobile System. The requirements include building and designing for use in an austere environment to provide heat and air conditioning through a mobile platform. These systems will be a part of a rapid deployment system that quickly responds to disasters, emergency, or special events to provide initial support to disaster victims or disaster management. It will be used for the immediate standup of a communications work center.

Capability:

50 Ton.

475,000 BTU Cooling 277,000 BTU Heating

Will cool and or heat a 16,000 Square Foot space

2.0 Generator

Heavy duty, 4-cycle, direct injection, turbocharged, air to air intercooled diesel engine provides maximum reliability.

Brushless alternator reduces service and maintenance requirements and meets temperature rise standards for Class F insulation systems.

Open delta alternator design provides virtually unlimited excitation for maximum motor starting capability.

Automatic voltage regulator (AVR) provides precise regulation.

Electronic governor system maintains frequency to ±0.25%.

Full load acceptance of standby nameplate rating in one step (NFPA110, para 5- 13.2.6).

Sound attenuated, weather resistant, steel housing provides operation at 75 dB(A) at 23 feet. Fully lockable enclosure allows safe unattended operation.

Internal fuel tank with direct reading fuel gauges is standard.

Seven stage powder coat paint provides durability and weather protection.

Jacket Water Heater (750 watts) for easy starting in cold weather climates (above 0° C).

Digital engine gauges including oil pressure, water temperature, battery volts, engine speed, and fuel level.

Analog generator instrumentation including AC ammeter, AC voltmeter, frequency meter, ammeter phase selector switch, voltmeter phase selector switch, and voltage regulator adjustment potentiometer.

ECU830 microprocessor-based digital generator controller.

• Remote 2-wire start/stop control.

• Operational temperature range of -40° to 85° C.

• High visibility LCD display with heated screen and alphanumeric readout.

• 50/60 Hz engine speed selection; engine is EPA dual-speed rated.

• Modbus interface for gauge panel and expansion options.

• DPF cleaning cycle indication.

Automatic safety shutdown system monitors the water temperature, engine oil pressure, low coolant, over speed, and over crank. Warning lights indicate abnormal conditions.

Complete power panel. Fully covered; three-phase terminals and single phase receptacles allow fast and convenient hookup for most applications including temporary power boxes, tools and lighting equipment. All are NEMA standard.

Fuel/water separator. Removes condensation from fuel for extended engine life.

Simultaneous single and three phase power.

Emergency Stop Switch. When manually activated, shuts down generator in the event of an emergency.
