Hercules Infitting Hinged Freezer Door

Hercules Infitting Hinged Freezer Door

The HERCULES Series In-fitting Hinged cold storage door is a cold storage system that is available in multiple thicknesses, widths, and heights. It is also applicable to multiple building design applications. Kingspan’s cold storage doors provide thermal performance of high R-value, superior airtightness and low thermal bridging, resulting in an energy cost savings of as much as 30% over traditional multi-part cold storage doors.

Control Circuit

Electronic control board with 5V logic. Options included: B2, E2 wiring, timer to close, mid-stop, delay on reverse, maximum run timer.


Manufactured by MANARAS: Opera-H-Jackshaft Operator with industrial duty motor for up to 25 cycles/hour or 100 cycles/day. Electronic control board supplied with floor level disconnect for manual operation.


An infrared photocell, detecting the presence of a pedestrian or a vehicle, immediately opens the door and keeps it open as long as the presence is detected. Height of the photocell: 12” from the floor (optionally up to maximum 24” upon request).

A bottom edge detector opens the door when it hits an obstacle during the closing cycle. This detector is positioned in the bottom part of the curtain.
