The Fusion Series, with airflow capacities ranging from 1,000 CFM to 70,000 CFM, pre-cools and dehumidifies the outdoor air during the cooling season and preheats and humidifies the outdoor air during the heating season. As a result, the outdoor air quantity can be increased from 5 to 20 cfm per person without increasing energy costs. As importantly, the first cost savings associated with the reduction in chiller and heating/humidification capacity typically pay for the added cost associated with the installation of the total energy recovery equipment. The SEMCO Fusion wheel has been developed to optimize total recovery performance and wheel pressure loss, while minimizing manufacturing cost. The Fusion has been designed for projects where the degree of contaminant transfer is not a major concern and where competitive pricing is considered most important. The Fusion wheel incorporates a proprietary zeolite composite coating and provides a contaminant carry-over performance that is superior to that offered by non-molecular sieve based wheels such as those employing silica gel.
