Precision Cleaning for
Critical Service Applications

In industrial process environments, cleanliness is more than a maintenance task—it is a critical requirement for safety, performance, and reliability. Haygor Instrument & Company provides specialized cleaning and contamination control services designed to prepare instrumentation for use in sensitive and high-risk applications where even trace contaminants can lead to failure or hazardous conditions.

Haygor supports a wide range of critical service cleaning applications, including oxygen, chlorine, nitrogen, and ethylene oxide (EtO) service. Each of these environments requires strict cleaning procedures and careful handling to ensure equipment meets safety standards and performs reliably under demanding conditions.

Specialized Cleaning Capabilities

Haygor provides cleaning services for a wide range of instrumentation and components, including:

Valves and valve assemblies
Pressure transmitters and gauges
Flowmeters and fittings
Manifolds, tubing, and hoses
Diaphragm seals and associated systems

Each cleaning process is tailored to the specific requirements of the application, ensuring compatibility with materials, process conditions, and industry standards.

Ethylene Oxide & Specialty Cleaning

For applications that cannot withstand traditional high-temperature sterilization, Haygor provides ethylene oxide (EtO) cleaning and sterilization services. This process is ideal for sensitive equipment and components that require controlled sterilization without thermal exposure.

EtO cleaning is performed in carefully controlled phases to ensure complete sterilization and safe removal of residual gases, delivering equipment that is both clean and ready for use in critical environments.

Engineered Cleaning for Critical Environments

Contamination in instrumentation systems can lead to inaccurate measurement, equipment damage, or in extreme cases, fire or explosion hazards. This is especially true in oxygen service, where residues such as oil or grease can create dangerous conditions.

Haygor’s cleaning processes are designed to eliminate these risks through a combination of mechanical cleaning, chemical treatment, and controlled inspection procedures. Components are carefully disassembled, cleaned, and evaluated to ensure that all contaminants are removed and that the equipment is safe for its intended application.

Controlled Cleaning Process

Haygor follows a structured and repeatable cleaning process to ensure consistent results:

Disassembly & Compatibility Check – Components are separated to isolate materials that may not be compatible with cleaning agents
Pre-Cleaning – Surface contaminants are removed using grinding, blasting, brushing, or swabbing techniques
Chemical Cleaning & Drying – Components are cleaned using specialized agents and dried with oil-free air or nitrogen
Inspection & Verification – Parts are inspected under white light and ultraviolet light to detect moisture, residue, or contamination
Final Assembly & Certification – Cleaned components are labeled, sealed, and reassembled if required, with testing and calibration performed when applicable

This multi-step process ensures that every component meets strict cleanliness and performance standards before being returned to service.

Why Cleaning Matters

Effective contamination control helps:

Improve measurement accuracy
Prevent equipment failure
Reduce safety risks
Extend equipment life
Ensure compliance with industry standards

In critical service environments, even small amounts of contamination can have significant consequences. Haygor’s disciplined cleaning processes help eliminate that risk and provide confidence in system performance.

A Trusted Partner in Critical Cleaning

With decades of experience in industrial instrumentation, Haygor brings the expertise, equipment, and attention to detail required for high-performance cleaning services. Our commitment to quality ensures that every component is returned in better condition—ready to perform reliably in the field.

Clean Systems. Reliable Performance.

Haygor’s Cleaning & Contamination Control services are designed to support safe, efficient, and dependable operation in the most demanding industrial environments.

Because when performance matters, cleanliness isn’t optional—it’s essential.

Remanufacture / Repair

Restoring Performance. Extending Equipment Life.

Haygor Instrument & Company provides comprehensive instrumentation repair and remanufacturing services designed to restore critical equipment to reliable, like-new performance. In demanding industrial environments, equipment failure can impact production, safety, and efficiency. Haygor’s repair capabilities help minimize downtime, reduce replacement costs, and ensure continued system reliability.

Rather than replacing failed components, many operations benefit from repair solutions that are faster, more cost-effective, and better integrated with existing systems. Repairing instrumentation allows components to remain matched to current processes, eliminating compatibility concerns while reducing lead times and overall expense.
