Save $2100.00 a Season with a two pump installation.
Norlock implements a two pump system designed to maximize efficiency while managing secondary refrigerant circulation.

The demands on the brine circulation system are not constant, less than 50% of the time, during start up or under heavy loads is an arena ice plant operating at its maximum capacity.
At capacity an ice plant requires a 25-hp pump to circulate the chilled brine. Typical in most arena installs, one big brine pump runs continuously costing approximately $6000 per season.

The fact is proper ice management only requires that much force less than 50% of the time. Significant energy savings can be achieved by running with a smaller pump during times of lighter loads.

For example, running with a 7.5-hp @ 50% of the time saves 42,298 kW.h or more importantly $2100 per season. Besides saving energy, the standby capability of an extra pump could be a real ice saver in the event of a pump failure.
