INSTALLATION
3.1 FACILITY REQUIREMENTS
3.1.1 POWER
The generator requires 200-240 VAC, single phase, 20A, 50/60 Hz. The system is supplied with a custom Y-style
power cord. One connector feeds the humidity generator via the upper cabinet receptacle; the other connector
feeds the air compressor via the lower cabinet receptacle.
The power cord is generally fitted with a NEMA 6-20 plug, however other plugs are available upon request.
3.1.2 COMPRESSED GAS SUPPLY
The system requires oil-free compressed air or nitrogen to operate and is supplied with an internal air compressor
that resides in the lower cabinet. The pressurized air is connected through an air hose to the upper cabinet of the
humidity generator.
The system may operate from this supplied air source, or from a user supplied external pressurized gas source. The
recommended pressure is approximately 90 psi but a supply pressure range from 60 psi to 150 psi is suitable. It
should be capable of providing a flow rate of approximately 20 liters per minute more. When utilizing your own
pressurized gas supply, it should meet the following minimum requirements:
Clean A general purpose 10 micron in-line air filter is generally sufficient to limit particle size.
Dry A pressure dew point of 20 °C or lower is recommended. Liquid water should not be present in the
air supply line if possible as this could overload the capacity of the humidity generator’s internal air
drier system.
Oil-free Oil within the air supply stream is one of the most harmful contaminants to a humidity generator as
it tends to coat the internal surfaces of the saturator, preventing it from producing the correct
humidity. While there are coalescing filters (for liquid oil removal), and activated charcoal filters (for
vaporous oil removal), these oil removal practices are not recommended as oil could still find its
way through the filters and into the system. It is best to start with an oil-free compressor. An oil-
free compressor eliminates the need for oil filtration / removal.
3.1.3 DISTILLED WATER
This system requires a source of distilled water for operation. The amount required depends on several factors,
including the humidity being generated, the temperature of that generation and the flow rate. For initial
operation, about 5 gallons of distilled water will be required. Additional distilled water will be required depending
on usage which is based on generated humidity, temperature, and flow rate. Generating high temperature, high
humidity, and high flow rate utilize the most water, while lower temperature, lower humidity, and lower flow rate
utilize the least. Plan on typical usage of about 1 gallon (4 liters) of distilled water per week.
