  • Superior Performance
    • EXCLU-SIEVE's unique flute geometry and desiccant surface provide higher transfer efficiencies and lower pressure losses than any other "heat wheel." This performance is independently certified in accordance with ASHRAE 84-78P and ARI 1060 recommendations. Your retrofitted system will perform more efficiently than ever before.
  • Patented Desiccant Surface
    • The patented desiccant surface excludes airborne contaminants while selectively transferring latent energy (water vapor) between the supply and exhaust airstreams. This is especially crucial for all applications where reintroduction of odors, such as toilet exhaust, is to be avoided.
  • Modular Media Sections
    • Modular media sections allow for the retrofit of existing heat wheels in the tightest of spaces. This directional flow media resists plugging, can be washed without affecting latent performance, and is protected by a corrosion resistant desiccant layer.
  • Light Weight Media Support
    • The media support members (hub, spokes and rims) are aluminum extrusions. This combines strength with precision to form the ideal sealing surface. These lightweight modular parts simplify the installation process, minimizing system down time and reducing project cost.
  • Variable Speed Drive System
    • The EXCLU-SIEVE retrofit can incorporate an optional A/C variable speed drive system with temperature controls to ensure precise, maintenance-free operation.
  • Factory Supervised Installation
    • Since most heat wheels are installed in systems serving critical areas, an efficient installation becomes as important as the quality of the equipment itself. Trained field technicians coordinate the entire retrofit project. In-house maintenance personnel are encouraged to participate in the EXCLU-SIEVE retrofit installation.
  • Standard Warranty
    • SEMCO EXCLU-SIEVE heat exchangers carry a standard limited parts warranty of 18 months from the date of shipment.
  • Extended Warranty
    • SEMCO offers an optional limited liability service contract of 18 months or 42 months that cover mechanical and performance deficiencies. For a complete description of the terms and cost of these service contracts, contact your nearest SEMCO representative.
