The HLL - 1700 high and low temperature impact test furnace is used to test the rapid conversion trial
from 1600 ° C to -60 ° C. High and low temperature zone adopted screw automatic control, the entire
conversion process can be complete in a relatively short time. The equipment is divided into three parts of
the high temperature zone, the low temperature zone and transition zone. With thermal processing between
each zone. Low temperature zone adopted the dual refrigeration system, and the cooling type have aircooled
or water-cooled for selectable.

Main function & Features:
1. Testing specimen quickly from the hot zone into the low temperature zone, can research material
     changes in the sudden heat quench, each temperature zone adopted unique isolation technology,
     independently of each other;
2. The furnace chamber of high temperature zone adopted imported alumina polycrystalline fibers
     material, with good thermal insulation properties, durability, and heating elements adopted imported
     silicon molybdenum rod with long service life; Low temperature using a dual refrigeration system to keep
     a long-term cooling;
3. Automatically operation and control, control systems used multi-step programming to meet a variety of
    complex test requirements; For remote centralized control we have software for optional purchase;
4. With over-temperature alarm, leakage protection, short circuit protection, compressor overload
     protection and lack water protection function, used safe and reliable.

Main Uses:
Widely used in the research of aerospace materials and the weathering test of special materials.
