Environmental and Stability Temperature Chambers

Peltier Cooled Temperature Test and Stability Chambers for Industrial, Semiconductor, and Pharmaceutical Industries

Environmental chambers provide supreme temperature testing for small, medium and large components and assemblies. The range of supported temperatures is -60℃ ~ 150℃, commonly used for mobile memory chips, Ci-MCP, LPDDR, SO-DIMM, electronic devices, software chips, and batteries testing.


We supply Peltier-cooled environmental temperature control chambers that feature automated process control, energy efficiency, and a vast range of features and performance options. They can be used for various applications including low temperature storage, shelf-life testing, stability testing, accelerated aging, and expiration date testing.


1DUT Chamber, Mobile Chamber, Mini Cold Open Chamber, Auto Door test chambers are ideal for steady-state temperature testing on a smaller and medium scale. These series meet the needs of even the smallest scale product testing and storage while ensuring quality throughout the entire process.


Environmental temperature test and storage chambers suit various types of environmental and performance conditions and are available in a variety of sizes and performance configurations.

Environmental and Stability Temperature Chambers | Peltier Cooled Chambers


Manufacturer of standard and custom temperature Peltier cooled environmental chambers used in medical, pharmaceutical, industrial, semiconductor, packaging, and defense industries.


LPR Global’s environmental temperature testing and stability chambers are designed to provide controlled temperature environments and are used for temperature stability testing and controlled storage applications where product life stability is critical with high volumes of samples can be incubated, tested or stored.


Temperature control units with Peltier or fin cooling technology are available in temperature-only configuration. Peltier effect cooled chambers minimize product loss risks caused by poor temperature uniformity by ensuring excellent temperature stability even with many samples on the shelves. Peltier cooled chambers operate efficiently and improve stability and accuracy of temperature control. Thermoelectric cooling is achieved by cascading two semiconductor elements when an electric current (AC or DC) passes through resulting in cooling or heating effect.

Thermoelectric Modules (TEC) for Coolers, Chillers, and Air Conditioners


Thermoelectric modules are semiconductor heaters which use the Peltier effect to create a heat flux between the two surfaces of the module. It works as a cooler or heater depending on the supplied current (AC or DC). TECs are used for low power applications and applications that require low and medium energy generation.


Lifespan of thermoelectric modules is affected by heat stress and fatigue between cooling surface and hear generation surface and, as a result, repeated fatigue accumulates in solder joint of TE elements. Our thermoelectric modules are bonded using thermal glue which is resistant to thermal shock and thermal expansion. Our technology has been recognized by the Korean Agency for Technology and Standards and approved for the use in the household water purification market in COWAY water purification appliances.


In addition to ceramic TEMs, we also offer Aluminum nitride (AlN) TECs for improved performance and temperature control and provide precision temperature technology between -40 ~ 120° degrees C.
