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, 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.

Regenerative Thermal Oxidizer (RTO) industries include:


Technologies to treat waste streams from Basic Chemicals (organic and inorganic chemicals, plastic resins, dyes, and pigments), Specialty Chemicals (adhesives and sealants, water treatment chemicals, plastic additives, catalysts and coatings) and the Agriculture Chemical manufacturing process.


Treatment of waste streams from chemical products derived from petroleum. Specializing in Acrylonitrile and Acrylic Acid processes by using multi-staged technology which results in exceptionally low NOx levels.


Systems to control the waste stream from processes where a crude or semi-finished substance (such as metal, oil, or sugar) is converted (refined) into a finished or higher-grade product.  


PCC’s technical solutions meet all aspects of Tier I, Tier II and Tier III manufacturing processes associated with the automotive industry. Treatment areas range from Dynamometer engine test stations to spray paint booth VOC elimination.


PCC offers alternative solutions to treat a wide range of process in the Pharmaceutical industry. Thermal and Biological Oxidation technologies, including Flameless Thermal Oxidation (FTO) are possible options.


PCC's diverse Oxidation technologies provide the end user with options specific to the treatment of dyes, flame-retardants and other chemical treatments used in the manufacturing and treatment of textiles.


PCC offers several options for the treatment of off-gases and other wastes associated with manufacturing. From simple to very complex systems, PCC can provide a suitable solution.


PCC has a full range of oxidation/combustion technologies to treat off-gases for most processes associated with the conversion of raw materials into products.


Multiple combustion/oxidation technologies make-up the PCC Solution for industries that are required to treat off-gases from the manufacturing processes specific to the production of non-ferrous metals such as aluminum, copper, and zinc; and ferrous materials such as steel. 


PCC’s Oxidation Systems offer both biological and thermal options for the treatment of off-gases and other waste streams associated with the processing, conversion, preparation, preservation, and packaging of foods, food by-products, additives, and beverages.  

Engineered Wood Products

PCC’s unique ability to offer technology options for the treatment of compounds, adhesives and naturally occurring compounds that are present in the off-gas waste streams from the drying and pressing applications utilized in the EWP industry.  Biological and thermal options are available to meet the control requirements of the manufacturer.

Pulp & Paper

PCC provides alternative solutions to treat a wide range of process in the Pulp & Paper industry. RTO and Biological Oxidation are the most compatible options.
