MRCOOL Universal High ESP 36,000 BTU Air Handler (MDUI18036E)

The Specialized Solution for High Static Pressure Applications

The MRCOOL Universal High-ESP Air Handler (MDUI18036E) represents a breakthrough solution for HVAC installations where conventional air handlers fail to perform. Engineered specifically for challenging environments like manufactured homes and complex ductwork systems, this specialized 3-ton (36,000 BTU) unit delivers exceptional performance where standard equipment simply can't compete.

Conquer Challenging Installations with Superior Static Pressure Capability

With an industry-leading static pressure capacity of 250Pa, the Universal High-ESP Air Handler stands in a class of its own. This exceptional capability enables the system to overcome significant airflow restrictions found in:

  • Manufactured and mobile homes with narrow, restrictive ductwork
  • Retrofit applications where existing ductwork cannot be modified
  • Multi-story installations with complex duct runs and multiple directional changes
  • Systems requiring long duct runs with multiple outlets

Rather than compromising on comfort and efficiency when facing these demanding scenarios, this specialized air handler maintains optimal performance where standard equipment would struggle with inadequate airflow, excessive noise, and premature component failure.

DC Motor Technology Delivers Efficiency and Performance

At the heart of this remarkable system is an advanced DC motor that fundamentally outperforms the PSC motors found in typical air handlers. This sophisticated motor:

  • Maintains consistent airflow across varying static pressure conditions
  • Delivers 1,000 CFM capacity with 8-speed modulation capability
  • Operates at just 47 dBA (quieter than a modern refrigerator)
  • Contributes to whole-system efficiency ratings up to 18 SEER
  • Provides superior humidity control through precise airflow management

The precision-engineered fan blade design works in harmony with the advanced motor to deliver exceptional airflow while maintaining whisper-quiet operation – a critical advantage in the space-constrained environments of manufactured housing where equipment noise can significantly impact comfort.

Installation Flexibility for Challenging Spaces

The MDUI18036E offers exceptional installation versatility with multi-position capability for upflow or horizontal mounting orientations. This flexibility proves invaluable when working within the confined spaces and unique structural constraints of manufactured housing and retrofit applications.

The unit's thoughtfully engineered dimensions (21-1/4"W x 21-1/4"D x 48-1/4"H) strike the perfect balance between compact footprint and performance capability, allowing installation in restricted spaces without compromising airflow capacity or serviceability.

Universal Compatibility with Critical Connection Options

Unlike proprietary systems that lock you into specific equipment combinations, the Universal High-ESP Air Handler works seamlessly with any compatible third-party condenser, including both heat pumps and cooling-only systems. This compatibility extends to connection methods, offering three distinct options:

  • Pre-charged No-Vac Quick Connect for simplified, tool-free installation
  • Traditional sweat/braze connections for conventional installation
  • Flare fittings for specialized applications

This connection flexibility eliminates the need for specialized tools in challenging installation environments and provides options when working within the unique constraints of manufactured housing.

Thoughtful Design Features for Real-World Applications

The Universal High-ESP Air Handler incorporates numerous practical features that address the specific challenges of high static pressure installations:

  • Robust condensation management with two-step protection system
  • Fire-proof electrical box with reserved circuit breaker space
  • Durable, washable metal filter (19-5/16" x 20-5/16" x 5/8") that resists corrosion
  • Auxiliary heat kit compatibility (5kW, 8kW, or 10kW options available)
  • Wide operational range from -5°F to 129.2°F for cooling and -22°F to 75.2°F for heating
Ideal Applications: Where Standard Air Handlers Fall Short

The MDUI18036E excels in precisely the applications where conventional air handlers struggle:

  • Manufactured and mobile homes with factory-installed ductwork
  • Attic installations with space constraints requiring horizontal mounting
  • Retrofit projects where ductwork modification is impractical or cost-prohibitive
  • Systems with extended duct runs requiring additional static pressure capacity
  • Multi-zone applications with complex distribution requirements

With its exceptional 10-year registered limited warranty and certifications from ETL, Energy Star, and AHRI, the Universal High-ESP Air Handler delivers the reliability and performance assurance essential for these demanding applications.

The MRCOOL Universal High-ESP Air Handler represents the specialized solution needed when conventional equipment simply won't suffice. By providing superior performance in the most challenging installations, this innovative system ensures comfort and efficiency in applications where compromise was previously the only option.
