Because of the complexity of controlling both parameters, every project is designed according to dimensions, material of the case, target values as well as ambient extremes in temperature and humidity. Although we do not have standard, off shelf units we are offering: Maxi T – Large units to control temperature and humidity inside the medium size cases (5-10 cubic meters) where main generator is located inside the machine room or other technical area some distance from the display case. See below. Mini T – small, compressor based unit for installation under or behind the display case. This unit can work with venting type or cooling/heating panels system. Will work with our Mini One or sometimes PMCG units. Special, thermoelectric device for very small cases. Will work with our PMCG unit. Please note that controlling temperature and humidity requires some changes to display case design and its very hard if not impossible

LPHC are , an acrylic-aluminium made humidification chambers designed to work with our Mini One microclimate generator. LPHC is offered in two standard sizes and also can be built as a special order in different sizes by client request. The body is made of black acrylic with aluminium and front doors from clear acrylic. RH levels are controlled through the Mini One microclimate generator. UNDER CONSTRUCTION CUSTOM STAINLESS STEEL CHAMBERS We are also offering special order microclimate chambers build to client specifications. Those units are constructed from stainless steel and depend on client expectations. All aspects of microclimate can be controlled: relative humidity, temperature and low level of oxygen can be attained. Chambers with controlled relative humidity and temperature can be built with glass doors (as in photo). Units with modified oxygen have solid, special sealed doors. Low level oxygen is generated using nitrogen generator or liquid nitrogen.

The Preservatech Mini One is a miniature humidity control device for museum showcases and storage enclosures. This robust and extremely efficient unit can reliably control humidity in individual or multiple enclosures. The Mini One active microclimate generator is a sixth generation system, satisfying the demanding standards of preventive conservation and modern museum design. It incorporates the most recent developments in electronic humidity control, noise suppression, and pollution abatement — built on the heritage of a family of microclimate control devices extending back to 1978. This positive pressure microclimate control system will typically maintain the relative humidity level in a sealed museum enclosure to within two percent (or less) of your target relative humidity. Depending upon the ambient temperature conditions and enclosure construction, relative humidity levels of less than thirty-five to over eighty percent can be attained.

Preservatech’s Maxi One constant volume humidity generator is a fully automatic positive pressure air supply device, designed to provide conservation-quality humidity control for museum display or storage enclosures. A single microclimate unit in a remote location (such as a machine room) can reliably maintain extremely stable humidity control and pollution abatement for an entire gallery of showcases. SUGGESTED APPLICATION: Use these units to supply air to multiple display cases, very large volume showcases, multiple storage enclosures or small archive rooms where: Energy cost savings of up to 50% are to be realized. Accurate humidity control in new or renovated galleries may be expensive or impractical. Existing air conditioning systems or building envelopes cannot maintain adequate humidity control.
