ONI Temperiertechnik RHYTEMPER® GmbH, Großröhrsdorf, subsidiary of ONI-Wärmetrafo GmbH in Lindlar, is a manufacturer of innovative temperature control solutions and is regarded as a leading company in the field of multiple channel temperature control – both in the plastic injection moulding and the metal pressure diecasting industries. Due to the widely diversified product spectrum of high efficiency multiple channel temperature control plants our company holds a globally unique position in the market.

In 2008, RHYTEMPER® Kunststofftechnik GmbH, Ottendorf-Okrilla, became ONI Temperiertechnik RHYTEMPER® GmbH. The move to a modern production building in neighbouring Großröhrsdorf took place simultaneously. A production and administration area of approx. 840 m² now made it possible to produce the high quality and energy cost saving temperature control solutions considerably more effectively for our customers.

Due to constantly increasing energy costs, strong pricing pressure on piece costs and the calls for constant demands on the quality of our customers' products, the focus of temperature control in injection and pressure diecast moulding is steadily becoming more strongly aligned with multiple circuit temperature control systems by ONI Temperiertechnik RHYTEMPER® GmbH.

The resultant permanently rising order situation occasioned the executive management to make fresh investment decisions in 2016 at the Großröhrsdorf location. Hence on the 26 June 2017 a move was made to the new business premises with approx. 1,350 m² of production and administration space.

Due to the consistent further development and optimisation of the system engineering as well as the commitment and willingness of our customer orientated and motivated team, we are securing the long-term market leadership in the field of temperature control technology and are convincingly underpinning why so many customers count on our products.

Our customer base includes notable companies such as the AE Group, Audi, BMW, BOGE, Bosch-Siemens, Faurecia, Grohe, Johnson Controls/Yanfang, Liebherr, Magna, Polytec, Röchling, VW, ZF and many more.

The success of the company is also impressively reflected in the credit rating index. After being reviewed and certified by Creditreform, ONI 2016 received a "very good" rating after being "awarded" last year. This is unique in the industry.

The innovative strength of ONI Temperiertechnik RHYTEMPER® GmbH has been recognised time and again through awards and honours. In this regard, for example, we received the "Innovationspreis der Euroregion Neiße" prize as far back as 2008.  ONI Temperiertechnik RHYTEMPER® GmbH has also been nominated every year since 2016 for the „Großen Preis des Mittelstandes“ by the city Großröhrsdorf and „EMS Ihr Beraterteam Hinner“. In 2016 we received the award as a "finalist" and since 2018 we have even been a prizewinner at the "Großer Preis des Mittelstandes".
