Product overview

WOWI Luft- und Klimatechnik GmbH is a service company offering a unified portfolio of HVAC (heating, ventilation, air conditioning) and refrigeration services, not a software product company. The core offerings consist of four interconnected service areas: Planung/Projektierung (planning and design), Anlagenbau (plant construction), Raumlufttechnik (HVAC systems), and Kältetechnik (refrigeration technology), supplemented by maintenance and service support. These services are provided through the full project lifecycle from initial planning and design through execution, commissioning, and ongoing maintenance.
