Services
Steam Trap Repair
Our technicians diagnose and repair steam trap failures to prevent energy waste and system inefficiencies. We conduct comprehensive surveys to identify malfunctioning traps, replace faulty components, and restore optimal performance. Clients benefit from reduced utility costs and extended equipment lifespan through our precision diagnostics and factory-certified repair protocols.
Valve Remanufacturing
We completely disassemble, inspect, and rebuild valves to factory specifications using machined replacement parts. Each remanufactured valve undergoes rigorous testing to ensure leak-free operation and durability. This service provides cost savings of up to 50% compared to new valves while maintaining compliance with industry safety standards for critical steam and fluid systems.
Heat Transfer Systems
We design and install plate & frame, shell & tube, and brazed plate heat exchangers tailored to commercial and industrial applications. Our systems optimize thermal efficiency in hot water heating, chilled water loops, and process fluid temperature control. Clients gain energy savings, reduced footprint, and improved reliability in HVAC and manufacturing operations.
Preventative Maintenance
Our Survey & Inspect program provides comprehensive analysis of control valves, regulators, and steam systems during scheduled visits. We identify potential failures before they occur, minimizing unplanned downtime. Facilities maintain consistent operations while extending equipment service life through our proactive maintenance strategies and detailed reporting.
Digital Control Packages
We integrate digital control systems for steam PRV stations and heat transfer applications, replacing outdated pneumatic controls. Our packages include programmable logic controllers (PLCs), remote monitoring capabilities, and energy management interfaces. Clients achieve precise temperature/pressure regulation, real-time diagnostics, and improved system efficiency for modern industrial and commercial environments.
