Company
EAW Energieanlagenbau GmbH is a company within the WEGRA Anlagenbau GmbH group with approximately 120 employees. Since 1995, the company has developed, produced and marketed energy systems for power, heat and cooling generation as well as waste heat utilization at its Thuringian site in Westenfeld (Römhild). The product range includes compact CHP units from 20 to 260 kW electrical output for natural gas and liquefied petroleum gas, absorption chillers of the WEGRACAL series with 15 to 400 kW cooling capacity (water/lithium bromide) and their combination as combined power, heat and cooling systems (CPHCS). In addition, LPG-powered emergency power generators, adiabatic coolers (WEGRACOOL), solar cooling solutions and process waste heat utilization are offered. Services include planning and dimensioning with profitability analysis, delivery, installation, commissioning as well as on-site service and emergency duty. Customers come from sectors such as hospitals, senior care facilities, industry, hotels, swimming pools, agriculture, food production and municipal utilities.
