T&S Klimaattechniek

What T&S Klimaattechniek does

T&S Klimaattechniek B.V. is a Dutch specialty HVAC and climate technology installer founded in 1999 and headquartered in Woerden, Netherlands. The company designs, installs, and services climate systems for two primary customer segments: datacenters (hyperscale, colocation, edge, and server rooms) and utility buildings (commercial offices, healthcare facilities, and industrial sites). Its core product portfolio spans chillers from 20 kW to 4 MW capacity, including oil-free Turbocor compressor chillers, CO2 heat pumps, precision air conditioning (CRAH/InRow DX), and 1 MW Cooling Distribution Units for liquid cooling. Equipment is sourced from OEM partners including Engie Refrigeration, Schneider Electric, and Rittal, with T&S acting as a value-added integrator and service provider rather than an OEM manufacturer. Since 2024, the company has been a wholly owned subsidiary of Nordic Climate Group Netherlands B.V., part of a Scandinavian platform of approximately 75 climate technology companies.

The company generates revenue through two principal streams: one-time project-based sales for design, supply, and installation of customized climate systems, and recurring service and maintenance contracts offered in four tiers (Standard, Standard Plus, Professional, Excellent All-In) with response times ranging from 24 hours down to 4 hours. A 24/7 remote monitoring and management service, delivered via the IXON Cloud IoT platform with multi-protocol support, backs the recurring contract base and currently covers 10,000+ managed installations with a "zero minutes downtime" claim. Go-to-market is exclusively direct enterprise field sales, supplemented by inbound referrals through OEM partners; the company operates Netherlands-wide with no third-party distribution channel. Recognitions include Schneider Electric Cooling Partner of the Year for 3 consecutive years, ISO 9001, ISO 14001, VCA, BRL 100, and EcoVadis Bronze certifications, with parent-level SBTi-validated climate targets.
