Welcome to Our World

WE REPAIR ALL MAKES AND MODELS OF REFRIGERATED AIR DRYERS

DryerServiceTech.com technicians possess a dual mastery of high-level HVAC-R thermal dynamics and industrial compressed air systems knowledge necessary to service, maintain and repair all makes and models of refrigerated air dryers that are found throughout the compressed air industry

• Refrigeration & Thermal Mechanics & Pressure-Temperature Analysis
• ·Calculating subcooling and superheat in real time to diagnose compressor inefficiency, refrigerant charge level, or expansion valve failure.
• Refrigerant Handling & Recovery: Universal EPA Section 608 certification level competency in recovering, leak testing, vacuum evacuation, charging, and silver brazing under pressure with modern refrigerants (R-134a, R-404A, R-407C, R-410A).
• Hot Gas Bypass Valve (HGBV) Tuning: Fine-tuning HGBVs and thermostatic expansion valves (TXV) to balance cooling capacity against fluctuating air loads and prevent heat exchanger freeze-ups.
• Compressed Air & Condensate Management Heat Exchanger Integrity: Servicing and pressure-testing air-to-air and air-to-refrigerant 3-in-1 integrated heat exchangers (aluminum plate or shell-and-tube) for internal leaks and fouling.
• Condensate Drain Diagnostics: Servicing and repairing zero-air-loss electronic drains, timed solenoid valves, and mechanical float drains.
• Oil/Water Separation & Air Standards: Understanding oil carryover, inline coalescing filtration, and air quality compliance per ISO 8573-1 standards.
• Electrical & Automated Controls Control Circuit Troubleshooting: Tracing complex electrical schematics, line diagrams, and ladder logic under live panel conditions. Component Testing: Diagnosing failing contactors, start/run capacitors, fan switches, pressure transducers, and crankcase heaters using digital multimeters. Digital Controllers & VFDs: Programming, reading fault logs, and calibrating digital dew-point sensors, microprocessor display boards, and variable-speed fan drives.
• System Load & Preventive Auditing Pressure Drop & Dew Point Auditing: Assessing inlet temperatures, ambient conditions, and pressure drop across the dryer module to isolate air-side vs. refrigerant-side restrictions.
• System Safeguards & Compliance: Strict execution of Lockout/Tagout (LOTO) protocols, ASME pressure vessel safety compliance, and proper disposal of contaminated condensate oil.

EPA Section 608 Certification Program

This webinar is ideal for air compressor service technicians or sales personal looking to obtain their EPA Section 608 Certification allowing them to legally (Hook refrigeration gauges up to refrigerated air dryers and to purchase regulated refrigerants. 

• Federal Regulations Section 608 of the Clean Air Act requires all persons who maintain, service, repair, or dispose of appliances containing regulated refrigerants, be certified in proper refrigerant handling techniques as required by the National Recycling and Emission Reduction Program. Regulated refrigerants currently include: CFC, HCFC, HFC, and HFO refrigerants. If you maintain, service, repair, or dispose of appliances containing a regulated refrigerant, you must be certified. You cannot work under another person’s certification.

• The EPA Section 608 Certification Program will provide the participant with the training and information that will make it possible to pass the EPA Section 608 exam and receive the EPA Section 608 certification.

Tuition to the program includes the following:

• EPA Section 608 Preparatory Manual
• 3 hour in person preparatory class
• Unlimited practice exams
• Closed book EPA Section 608 certification exam supervised by an EPA approved Proctor
• Testing re-takes (If necessary)

Upon competition of the EPA Section 608 Certification Program and passing the exam the student will receive the following certifications

• Core Certifications
• Type I Certifications
• Type II Certifications
• Type II Certifications
• Universal Certifications

Upon competition of the EPA Section 608 Certification Program and passing the exam the student will receive the following certifications:

The student that receives the above certifications will legally be able to maintain, service, repair, or dispose of appliances containing regulated refrigerants and purchase regulated refrigerants from local wholesalers.
