Refrigeration and Air Conditioning
Hampden's Heating, Refrigeration,
and Air Conditioning training programs, which include basic principles through advanced
industrial systems, utilize actual commercial components throughout. These training
programs follow curriculum guidelines developed by the Air
Conditioning and Refrigeration Institute (ARI) and the Association of Home
Appliance Manufacturers (AHAM). For this reason Hampden equipment is widely used in
secondary and post-secondary vocational schools, community colleges, and technical
institutes.
Furthermore, Hampden's Training Equipment is
manufactured to operate at the specific voltage and frequency of the country in which it
is to be used. Consequently, heating and refrigeration technicians all over the world are
being trained with the help of Hampden Educational Systems.
Hampden offers the widest selection of basic,
intermediate, and advanced programs. This provides the consistency so vital to vocational
and skills training. For advanced automation training, Hampden’s Heating,
Refrigeration, and Air Conditioning trainers may be equipped with the sensors and signal
conditioners required for automatic data acquisition, logging, processing, and control.
Additionally, the trainers may incorporate electrical indicators and instructor-programmed
faults.
Hampden trainers contain
EPA-approved, non-CFC, environmentally safe refrigerant.
