Standard Configuration
Programmable controller with backlit touch keys, six-speed fan, motorized air damper, preheating chamber, slide-out shelves, dual-stage door lock and one RS-485 interface. Overtemperature protection uses the temperature sensor system and an independent temperature switch.
Optional Accessories
Inlet and exhaust air filters, extra shelves, printer, monitoring software and GPRS alarm messaging are optional. Confirm compatibility and scope in the quotation. No software compliance or validation service is included by default.
