Why "BeO-Free" Matters
Beryllium Oxide (BeO) is a ceramic often used in RF resistors for its thermal conductivity, but it is highly toxic if machined or pulverized. COM-TECH was the first to introduce a complete line of BeO-Free Dry Loads, using advanced alternative ceramics that offer equal thermal performance without the health hazards.
- Safety: No risk of toxic dust contamination during handling or failure.
- Compliance: Fully RoHS and ISO 14001 compliant.
- Maintenance-Free: No oil levels to check, no leaks to clean.
Product Series
1. Dry Loads (DH, DL, DT Series)
Designed for natural convection or forced-air cooling, these loads are the workhorses of the industry. They feature a compact aluminum heat sink design that can be mounted in any orientation.
- DH Series: Low power (10W โ 90W)
- DL Series: Medium power (250W โ 800W)
- DT Series: High power (1.1kW โ 3.5kW)
- Cooling: "H" (Heatsink) standard, with forced air options for higher densities.
2. High-Power Liquid Cooled Loads
For high-power transmitter combining and termination, COM-TECH offers liquid-cooled variants. These compact units use a coolant loop (water/glycol) to dissipate massive amounts of heat efficiently, replacing the need for bulky oil drums.
3. The "DP" Power Load Series
The DP Series bridges the gap, offering robust power handling (2.5kW โ 5.0kW) in a standalone chassis, ideal for test benches and combiner reject loads.
