Innovation and Quality have always been the foundational building blocks of the HTS philosophy: offering innovative high end products is the basis for maintaining the success of HTS in the European market. HTS quality is constantly being reinforced by intensive staff training and improvements to production processes.

2 Year Guarantee

All products are manufactured with high quality materials and undergo stringent quality tests. They are therefore guaranteed against defective workmanship and material for a period of two years from the date of shipment.

Warranty terms

Any damage caused by corrosive agents is excluded. If a defect should develop, return the equipment or the part, with prepaid freight, to the HTS factory where it will be checked and replaced or repaired at the discretion of HTS. No liability is assumed for damage caused by the proper use or misuse of HTS products. No guarantee is granted in the event of the wrong or incorrect use of the products. HTS reserves the right to make changes in specifications or design at any time, without notice and without obligation to purchasers or owners of previously sold equipment.


Certification covers all the products in a range and is awarded only if the results of the tests conform to the values reported in the catalogue. The certification stipulates an annual verification of some models in the range, always chosen at the discretion of Eurovent. Checks are carried out on random samples of the products being tested. These tests are performed at the premises of highly specialised international institutes. Any deviation from standards must be corrected throughout the entire range; otherwise, the certificate is revoked. This certification system ensures that the designer, installer and final user has an extra guarantee: they have chosen components, which are ideal for approved refrigeration and air conditioning equipment, and this equipment operates at optimal conditions and at minimum costs for its entire life cycle.
