Pass-through Oven UF TS - Memmert

Temperature-Controlled Cleanroom Material Lock

The Memmert UF TS is a pass-through drying oven engineered as a temperature-controlled material lock for cleanroom laboratories. With fully insulated stainless steel doors on both sides, it allows samples and components to be heated, dried and passed between the grey room and the cleanroom while minimising the risk of contamination. It is widely used in the electronics and semiconductor, pharmaceutical and medical industries.

Built on the Proven UFplus Platform

The UF TS is based on the Memmert standard heating oven UFplus and inherits its forced air circulation, homogeneous temperature distribution and fast recovery times after the door is opened. The corrosion-resistant, easy-to-clean stainless steel interior is designed for the demands of cleanroom operation, and the oven reaches working temperatures up to +250 °C.

Precise, Programmable Control

The top configuration with TwinDISPLAY ensures precision and thermal safety when working at the cleanroom interface. An adaptive multifunctional PID microprocessor controller with two high-definition TFT colour displays drives the process, while the AtmoCONTROL software lets users program temperature and air exchange ramps. Electronic air exchange rate control, an electronically adjustable pre-heated fresh air intake and an internal data logger give full command and documentation of every cycle.

Sizes and Configuration

The series is available in four chamber sizes — UF160TS (161 L), UF260TS (256 L), UF450TS (449 L) and UF750TS (749 L) — so the oven can be matched to the required throughput. It can be equipped with lateral feed-through accommodating deflection rollers for quick throughput when manufacturing electronic components, and includes electronic temperature monitoring with a mechanical limiter, an integrated auto-diagnostic system and a 3-year worldwide warranty.

Frequently Asked Questions

What is the Memmert UF TS pass-through oven used for?
The UF TS is a temperature-controlled material lock designed for cleanroom laboratories. With insulated stainless steel doors on both sides, it lets samples and components be heated, dried and transported between the grey room and the cleanroom while minimising contamination in the electronics and semiconductor, pharmaceutical and medical industries.
What temperature range and accuracy does the UF TS offer?
The working temperature range extends from at least 10 °C above ambient temperature up to +250 °C. Setting accuracy is 0.1 °C up to 99.9 °C and 0.5 °C from 100 °C and above, measured with two Pt100 Class A sensors in a 4-wire circuit.
Which sizes are available?
The UF TS series is offered in four sizes: UF160TS (161 L), UF260TS (256 L), UF450TS (449 L) and UF750TS (749 L), so the oven can be matched to the throughput required at the cleanroom interface.
How does the oven help prevent cleanroom contamination?
It uses forced air circulation with an adjustable turbine and an electronically adjustable, pre-heated fresh air intake, combined with electronic air exchange rate control and monitoring. The easy-to-clean stainless steel interior and fast temperature recovery after door opening keep conditions stable as material passes through.
What control system does the UF TS use?
The TwinDISPLAY top configuration provides an adaptive multifunctional digital PID microprocessor controller with two high-definition TFT colour displays and menu navigation in eight languages. Temperature and air exchange ramps can be programmed with the AtmoCONTROL software, and an integrated data logger records process data.
What safety and warranty features are included?
The oven includes electronic temperature monitoring with a mechanical temperature limiter, an integrated auto-diagnostic system and multiple interfaces for documentation. Memmert provides a 3-year worldwide warranty.
