HVAC Systems
Ellis & Watts specializes in custom engineering and manufacturing safety- and non-safety-related HVAC systems for mission-critical industrial applications such as nuclear power, military, aerospace, hazardous waste processing, and research laboratories. We offer complete custom flexibility on systems, components, and spare parts engineered for critical performance in harsh environments, and we are committed to servicing them for life.
Ellis & Watts HVAC systems and components can be designed to meet specific project requirements - CLICK TO SEE FULL LIST
- a wide range of performance capacities
- extreme ambient temperature conditions
- corrosive and radioactive environments
- critical pressure and leakage performance
- weight and space restrictions
- efficiency, reliability, and life-cycle cost objectives
- analog, relay-based controls to address qualification, cyber security, or EMI/RFI concerns or digital control systems
- impact, shock, and vibration requirements, including mobile applications
- modular construction to address on-site transportation, rigging, and installation constraints
Equipment can be factory performance tested at full- and part-load conditions to document compliance and assure proper operation. Tests can be performed within a wide range of ambient temperatures and humidities to simulate design conditions. EMI/RFI verification testing is also available.
