The PCC Difference

Compare the PCC RTO with any others and you'll find these distinct advantages:

Mechanical Valve Drives – So Good, They're Patented

The heart of our RTO is the patented electro-mechanical 4-way poppet valve system. This valve and control system is designed to eliminate the continuous maintenance brought about by the endless movement and slamming of the disk in typical poppet valve RTOs.

Our proven patented mechanical valve drive system operates the flow control dampers smoothly in both two chambers and larger multi-chamber designs. The two valve discs are concurrently reversed by a common camshaft that intermittently, but consistently moves the valve disks between seats in less than 1/2 second. 

The result?

  • Virtually no pressure spikes and contaminant bypass as the valves are tied to one camshaft and operate in unison
  • No leaky/erratic hydraulics that change frequency as the weather dictates
  • No moisture freezing pneumatic lines and cylinders
  • Best of all, no need for maintenance intensive pneumatic or hydraulic operators. This feature alone will substantially increase your savings by minimizing maintenance and equipment downtime.

Integrated Manifolding

The PCC RTO assembly incorporates the inlet and outlet exhaust manifolds into the RTO's overall shell configuration, rather than fabricating the typical network of bulky, exterior space-consuming manifolds. This eliminates external RTO ductwork and insulation, enabling the system to sit flat on a concrete pad without legs.

This streamlined assembly design decreases maintenance costs and creates a compact footprint that is cost-effective to both manufacture and installs.

Exclusive, patented heat recovery media

Our ceramic heat recovery media is an exclusive, patented ultra low-pressure drop media specifically designed for use in PCC's RTOs. The combination of high heat recovery with low-pressure drop results in significantly lower gas and electric usage, as well as higher VOC destruction efficiency, making it one of the most environmentally responsible pollution control units available today.

How PCC's RTO Works

The premise of PCC's RTO design is as simple as 1-2-3:

  • Heat is extracted from the hot purified gas and stored in the reheat recovery chamber as it leaves the combustion chamber.
  • After a period of time, the inlet/outlet valves switch positions and the contaminated process gas is redirected through the hot heat sink recovery chamber (containing Cell Stone® Ultra heat recovery media), where it is preheated to within 5% of the combustion temperature before it enters the combustion chamber.
  • In the combustion chamber, the burner supplements the 5%, bringing its temperature to 1500° F, at which the VOC is converted to harmless CO2 and water vapor.
