CAT GAS RATING DEFINITIONS
Standby PowerThese ratings are applicable for supplying continuous electrical power (at variable load) in the event of a utility power failure. No overload is permitted on these ratings. Natural gas ratings have been established on natural gas with net calorific Low Heat Value (LHV) of approximately 35.6 MJ/m3 (905 Btu/ft3) and 80 methane number (MN).
Continuous PowerOutput available without varying load for an unlimited time. Continuous power in accordance with ISO8528, AS2789, and BS5514.

Note: Additional tank capacity required for cooling of recirculated fuel in unit-injected engines. Tank should be located below level of injectors or nozzles.
On-Site Power RequirementsBased on 100,000 sq ft. of office bldg., etc and 40°N. Latitudes
• Electric Requirements 600 kW continuous load (Air conditioning is absorption) Use three - 300kW units (2 prime and 1 standby)
Refrigeration • One ton refrigeration = 200 Btu/min = 12,000 Btu/h • One Boiler hp = 33,475 Btu/h • One ton compressor rating = One engine hp • Auxiliary air conditioning equipment requires 1/4 hp/ton of compressor rating
Ice Plant • Complete power requires 4-5 hp per daily ton capacity
Air Compressor • hp = 1/4 x cu ft m/min at 100 psi Increase bhp 10% for 125 psi Decrease bhp 10% for 80 psi

ENGINE ROOM VENTILATION
Engine room ventilation can be estimated by the following formulas, assuming 100°F (38°C) ambient air temperature:
V (cfm) = H + Engine Combustion Air 0.070 x 0.24 x T
V (m3/min) = H + Engine Combustion Air 1.099 x 0.017 x T
V = Ventilation air (cfm) (m3/min).H = Heat radiation (Btu/min) (kW). T = Permissible temperature rise in engine room (°F) (°C).Density of air at 100°F = 0.070 lb/cu ft (1.099 kg/m3).Specific heat of air = 0.24 Btu/°F (0.017 kW/°C).

COMPARISON OF REDUCED VOLTAGE STARTING METHODS
*Resistor starting adds considerable kW load to generator set. Total power required includes the motor kW and the kW which is lost as heat in the resistor. The series resistors account for a higher than normal starting power factor.

A • Customer Support Agreement (CSA) is an arrangement between the end user and the Cat Dealer that helps lower the cost per unit of production.
Agreements are tailored to fit your business needs and can • range from simple Preventive Maintenance Kits to sophisticated Total Cost Performance Guarantees.
Trained dealer technicians assist you by maintaining your • equipment and driving down operating costs. Perhaps the most important feature of any CSA is flexibility.
A • Preventive Maintenance (PM) agreement covers specified maintenance at a fixed cost. You maintain reliability and efficiency because the maintenance is performed by highly skilled technicians at guaranteed costs, giving you the ability to budget more accurately.
A • Total Maintenance and Repair (TM&R) agreement covers all of the maintenance and repair costs. Instead of paying for maintenance or repairs as they are needed, you pay one flat rate to cover a broad range of parts and services.
Check with your local Cat dealer for available options with each agreement.
