Emerson manual Nominal High-Stage Capacities, High Stage capacities 450XL ratings

Nominal High-Stage Capacities

With its 114 mm bore and stroke, the 450XL provides up to 30% more capacity than similar size compressor units, all while main- taining a favorable COP ratio.

Nominal high-stage ratings for the 450XL are shown in Figure 1 below.

Complete detailed ratings for all 450XL high-stage models, plus rat- ings for 450XL booster compressors, special high suction pressure compressors, and even integral two-stage compressors, are avail- able for all major refrigerants either from the Vilter Sales Offices.

Cooling Capacity (kW) Absorbed Power (kW)

Saturated Suction Temperature °C

These ratings are establised under the following conditions:

•1200 RPM

•Saturated suction

•No subcooling

•No belt losses

•All ratings are based on 60°C condensing temperature

•Ratings are based on a 4-cylinder 450XL (454XL).

For cooling capacity and approximate kW figures of other 450XL models, use a direct proportion to the number of cylinders of the 454XL. For example, use a 3.0 factor for determining the 12-cylin- der 450XL cooling capacity and approximate kW figures.
