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 an arena ice plant is operating at its maximum capacity, even during start up or under heavy loads. 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.
