Straus Engineers are available to consult on your building design. In addition, today’s energy management requires a commitment to ensure that a total mechanical system can meet the rigid energy requirements. Straus System’s technical support along with application experience will enable the HVAC system to be designed to fit your needs.

Insulation for each mechanical system must be selected based on the need of the application. The application of insulation is a prime factor in the total performance picture.

Equipment Modifications

Straus has set aside a portion of the shop to modify HVAC and Refrigeration equipment for use in industrial plants. There are many areas within the industrial plants where potentially explosive environments exist. The equipment that is installed and operating within these areas must meet stringent National Electrical Code (NEC) standards to avoid “sparking”. We, at Straus, are capable and experienced in making these necessary conversions to meet these rigid standards. We not only do it on the equipment that we supply but we are often asked to do it by major HVAC and Refrigeration equipment manufacturers.

Equipment Modification Work includes:

  • Explosion proofing modifications
  • Chemical resistant coatings
  • Skid mounting of HVAC and Refrigeration systems
  • Chiller and Condenser Vessel retubing and repair
  • Modification of control systems
  • Custom design and fabrication of HVAC and Refrigeration systems
