OPTIMUM HUMIDITY

Wet environments can cause problems in buildings, ships, steel structures and pipelines. Excessive moisture and dampness leads to mould, corrosion and short circutting. Dehumidificaton is essential

Too little moisture results in dry climates in offices, museums, art galleries and archives. Humidification is the soultion

Ship and offshore

On board ships and oil platforms there is a requirement for both dehumidification and humidification. Regardless of how well a ship or oil platform is maintained, certain areas will always be exposed to corrosion.

Supplying these areas with dry air helps keep rust development to a minimum. Even untreated steel stops rusting when the relative humidity is kept below 45 per cent.

Unaccountable system failures and breakdowns are mainly caused by dampness because electronics and motor windings are sensitive to moisture. By installing adsorption dehumidifiers, the inner climate can be controlled and repair costs considerably reduced.

The Norwegian Coast Guard

Cold and damp spaces in ships hulls have presented the Norwegian Coast Guard with maintenance problems. High humidity in equipment rooms containing electric motors, pumps and other installations has resulted in high maintenance costs.

The KV Andenes and KV Nordkapp have now installed adsorption dehumidifiers. These ensure optimum humidity and the Coast Guard anticipates a reduction in maintenance costs. So far, the results have been good.

The Kristin platform

F-Tech has delivered adsorption dehumidifiers to Statoils new Kristin platform. Dehumidifiers safeguard external pipe systems and electronic connections against corrosion and condensation problems. Dry air is pumped into open cavities and service ducts and keeps dampness and maintenance under control.

CRP dehumidifiers from HBC

The CRP dehumidifier series is designed for process air drying, ie. applications of low dew points or deep drying.
For this application the dehumidifier often is connected a pre- and/or post cooler. Process drying needs very reliable equipment, and due to the special high quality components used in the CRP series, this high reliability isachieved. The CRP series dehumidifiers is the top-quality process dehumidifiers.

THE CRP DEHUMIDIFIER FEATURES:

Cabinet manufactured in stainless steel
Designed for low dew point applications
Designed for easy connection of external AHU parts
The insulated inlet plenum allows for pre-cooled process air
Electronic controller for stepless temperature control (reg.air)
External pressure available for dry air and reg.air for ducting on site
Pocket filters for process air inlet, filter cassette for reg.air inlet
Internal components of highest quality and reliability
High performance desiccant rotor of washable silica gel
Separated air flows for process air and for reg.air, two fans installed
Easy access for service and maintenance
Electric-, steam-, or gas heater available.

AREAS OF APPLICATION.
The CRP range is designed for process drying. Process drying is often a process of drying fresh
air to a low dew point, a process that often needs a pre- cooler for the first dehumidification step,
then the CRP dehumidifier for the low dew point, and finally a post cooler for the temperature
control of the dry air. A combination of standard AHU components connected our standard CRP
dehumidifier, ensures the highest quality of the critical part: the dehumidifier.

CONTROLS.
our electronic hygrostats DA20 and
DH24 or our
For controlling the CRP series dehumidifiers we recommend
advanced microprocessor based Dehumidifier Control Centre, DCC.
The DCC controls the dehumidifier on %RH and/or dew point.
Internal alarms and temperatures of the dehumidifier can be displayed, aswell as the control
parameters can be setup in the DCC remote panel. External values of temperature, %RH and
dew point for up to 3 sensors can be displayed. The DCC offers on/off and stepless control of the
dehumidifier, allthough the CRP series dehumidifiers needs an optional component in order to use
the stepless control.
