The System 2 products are the low-cost, simple-to-install, quietventing solutions for mid-size heat loads in mid-sized cabinets (and mid-sized budgets!).
The family has 3 members - the original System 2, the 2 Kit, and the 2+2 Kit. All feature automatic temperature control, relieving the system designer of control issues. As equipment warms, fans begin to turn. if temperature rises further, the System 2 Kit and 2+2 Kit switch to a higher but still very quiet speed. Speed limitation and the use of multiple fans ensure effective cooling with very little noise.
The original System 2 has 2 fans and drive electronics on a 1/8" black mounting plate, and is usually mounted on the back of a cabinet to exhaust hot air.
The System 2 Kit (with 2 fans, for most mid-sized cabinets) and 2+2 Kit (with 4 fans, for the larger cabinet or larger heat load) consist of "separates": fans, fan guards, drive electronics in a small box, power supply, and a remote temperature-sensing thermistor. Both Kits are ideal for building into an enclosure at the planning stage. (Or retrofitting into existing installations that are running hot.) Fans and temperature sensors come with long wires for an easy, plug-together, no-soldering installation.
