Origin：China

Product Summary

Variable airflow, power consumption reduced by over 30%, an environmentally friendly constant temperature oven that reduces CO2 emissions

Features

Equipped with variable airflow mechanism: 10-step variable airflow (411C/611C) + airflow [0] (stop), 10-step variable airflow (811C/911C)

Achieve 30% energy-saving during constant temperature operation through airtight thermal insulation in the chamber (compared to previous products)

Maximum temperature reach time shortened by up to 15 min (compared to previous products)

Standby time and recovery time are also reduced, achieving operational efficiency

High airtightness prevents dust and debris from entering the chamber

Fixed temp

operation, 99 segments program operation, auto stop operation, auto start operation

Temperature and time setting displays, deviation corrections, etc

, can be achieved through the VFD fluorescent display

Various optional features allow for system upgrades based on user needs

Safety: Equipped with self-diagnostic circuits, independent overheating preventers with digital settings, overcurrent leakage protection, key locks, and other safety functions
