Commercial Water King Size Selection
Pipe Diameter
Having decided where to locate the Water-King, select the appropriate sized unit according to the pipe diameter. If hot water is provided by a Direct Fired water Heater then select the larger size according to maximum output rating.
Direct Fired Water Heaters
We recommend maximum heat ratings for different sized units and this also varies according to whether they are gas fired, oil fired or heated electrically.
Flow Rate
Flow rate is immaterial as far as Water-King is concerned. The greater the flow, the more effective the units tend to be.

Self-Diagnostic "Guard chip"
Every computer system is prone to malfunction, especially if there is a sudden variation in the power supply which can jam the program. Normally the system has to be reset by manually re-booting. Water-King units overcome this problem by an additional "Guard Chip" program which monitors the performance of the main program and resets the system automatically if it detects a variation or system failure. There is no need for manual resetting after power outage.
WK1 - A simple to fit DIY unit with external transformer. This unit has "Guard Chip" protection. The external transformer is available in a full range of pin configurations and supply voltages
WK2 - An intermediate sized unit with "Guard Chip" and external transformer. The extra pair of aerials can be used for treating a second pipe as well as reinforcing the signal applied to a single pipe.
WK3 - A powerful unit that will handle the majority of commercial applications. It is frequently specified to treat the cold supply to direct fired water heaters and paired with a Wk1 on the secondary return. It has output for a Building Management System to detect power failure.
WK4 - This unit is designed to treat larger pipe sizes up to 105mm. It has mains input with integral transformer, normally rated at 230 volts, but UL-approved 110 volts transformers can be supplied as an option. The enclosure is rated IP65
WK5 - This is the largest standard Water-King unit with the same dimensions, transformer options and features as the WK4. It has six aerial outputs arranged as three pairs and is capable of treating pipe sizes up to 159mm.
