As specialists in the maintenance, repair, and calibration of environmental chambers, at H&H Environmental Systems we offer a comprehensive lineup of technical support services. Along with providing repair, retrofit, and upgrade services on an as-needed or emergency basis, we administer “Repair Before Failure” (RBF) programs that integrate real-time monitoring with preventive maintenance. We service all types of equipment, from temperature, humidity, altitude, and combined environment chambers to HALT/HASS test equipment, shock chambers, walk-ins, and steady-state environment test chambers. With our dedicated service philosophy, we ensure our customer’s environmental test chambers perform with the highest degree of accuracy and reliability.

Whether requirements involve a minor repair or a complete chamber reconditioning or overhaul, we offer turnkey support for all aspects of environmental chamber maintenance and repair. In addition to carrying out comprehensive test programs for chamber validation and qualification, we provide custom touchscreen HMI software implementations and PLC controller retrofits and upgrades for PID control, over/under monitoring, I/O expansions, data logging, and more. We offer state-of-the-art networking solutions for remote monitoring, programming, and off-site alerting as well as retrofits to EPA certified oils and refrigerants.

Specifically tailored to customer requirements, we offer RBF preventive maintenance plans where we service equipment on a pre-determined schedule. Programs can also include remotely connected, real-time service monitoring of oil and refrigerant pressures, electrical anomalies, as well as maintenance and calibration cycles. With electronic recordkeeping, our customers are kept apprised of all schedules, repair activities, and daily progress. By implementing RBF programs to keep environmental chambers performing reliably and operating efficiently, we help customers reduce the risk of a major breakdown while extending the service lifecycle of their assets.

With our extensive history in environmental chamber maintenance and repair, we support industries including aerospace, HVAC, military, packaging, cryogenics, consumer goods, semiconductors, robotics, medical devices, and much more. Contact us today for more detailed information or to make an inquiry.
