PrecisionPower TCU is a Thermal Control Unit designed to improve the heat dissipation of PrecisionPower Art Series amplifiers. It uses a liquid cooling system to transfer heat away from the amplifier, resulting in lower operating temperatures and improved performance. The TCU can be used with any Art Series amplifier to provide additional cooling capacity, which is especially beneficial in high-power applications or in environments where heat dissipation is limited. The TCU includes a reservoir, pump, heat exchanger, and necessary tubing and fittings for installation.
