With the acquisition of the OdorEyes company, Welker secured a knowledge and experience base that has now been added to with engineering  products that have brought a new dimension to odorant injection so long considered a problem area. With increasing demands from regulators for operators to adhere to stringent limits of odorisation, there is more demand for odorant systems that meet a huge range of injection rates and in locations that previously were not considered as practical sites for odorant systems.
Haldatec have for years provided systems ranging from major pipeline installations, to installations on suburban blocks and small industrial customers, with the associated demands for system sophistication to economical simplicity, whilst maintaining high accuracy of odorant levels.
We can supply items of equipment to add to or replace existing installations, complete systems with or without tanks, with or without odorant, giving users complete freedom of choice, now, and importantly into the future.
We do not have standard packages. Each one is designed and built to cater for individual needs - we understand one size does not fit all!

Bypass

Traditionally Bypass odorant systems were wick or a flow metered, accuracy over a range of flow was difficult if not impossible to maintain. OdorEyes and Haldatec can offer bypass systems that vary in complexity whilst still maintaining accuracy. These systems are particularly suited to smaller installations.

Direct Injection

Gone are the days of unreliable leaky pumps and wasted odorant. Our injection systems use equipment that leapfrogs offerings from elsewhere, with a fresh approach that extends equipment life and maintenance periods and at the same time does not waste odorant as traditional systems do. We are conscious of all the reservations users may have towards these installations and have addressed them with easy to use, reliable, flexible equipment, right down to the fittings!
