    OPTIMUM PROTECTION FOR SENSITIVE READINGS

Stainless steel sensor wells.

We deliver optimal protection for sensitive readings.

Stainless steel sensor wells

Optimum sensor protection in building services engineering

Our stainless steel sensor wells contain the most sensitive component in measuring technology: an NTC thermistor. This is because reliable measurements in heating, ventilation, air conditioning and plumbing systems are essential to ensure precise adjustment of the energy used. This guarantees an unchanging measurement environment for years to come,  saving costs and protecting the environment.

»WELL PROTECTED – WHAT REALLY COUNTS«

Manufacturing

Manufacturing

Fully automated efficiency

Automated production in Lollar currently enables us to mass-produce more than 1.7 wells a year. We upgrade our production systems consistently on a continuous basis while taking into account environmental factors. We are leaders in thermowell and sensor well production in Europe.  

Protection

Protection

High-grade and durable

100% quality inspections (pressure and inside diameter check) ensure wells are perfectly safe for our clients. They receive high-grade products which provide reliable protection for sensors for many years and thus obtain uniform measurement readings.

Accessories

Accessories

For reliable measurement readings

Matching accessories make it easier for you to install sensors. Other accessories ensure that an unchanging measurement environment is maintained to provide uniform measurement readings. We have all the accessory parts that you require and will gladly advise you on what you need.

Certified quality – documented and assured

We submit all thermowells to a pressure test and inside diameter check with leak tests on request. We verify other parameters during sample checks. 

The process is documented in an inspection record. This ensures that materials and activities can be traced in line with ISO 9001:2015.
