Clima-Tech®: The All-In Climate Control Solution

Mobile HVAC has long had a problem: climate control is fragmented across three power states. Engine-on uses engine-driven components. Engine-off requires auxiliary systems. Shore power adds another layer: different controls, different interfaces, constant manual adjustments.

The Clima-Tech^® – Advanced Climate Control System with E-Breeze integration eliminates these boundaries.

One System, All Power States

Traditional systems require operators to reconfigure controls whenever the power source changes. Each transition risks user error, temperature swings, and wasted time.

Clima-Tech^® with E-Breeze adapts automatically. With either engine power, battery power, or shore power, the system maintains consistent cabin comfort without operator intervention. One interface. One set of controls. Zero friction between power states.

Engine-On: Intelligent Optimization

With the engine running, Clima-Tech^®‘s Auto Mode continuously monitors the inside and outside temperatures and operational demands. It adjusts compressor operation, condenser fans, blower speed, and water valves to maintain set points within 1°F.

Colour-coded backlighting provides instant feedback: red for heating, blue for cooling, green for maintaining air movement. Operators know the system status at a glance.

Engine-Off: Seamless Cooling

Engine shutdown traditionally ends air conditioning. E-Breeze changes that with a battery-powered electric compressor that delivers full cooling capacity without the engine.

When integrated with Clima-Tech^®, the transition happens automatically. No interface changes. No manual switching. The system shifts from engine-driven to battery-powered cooling while maintaining identical operation.

This matters for emergency vehicles on scene, work trucks during breaks, and service vehicles between stops. Comfortable working conditions without fuel burn, engine wear, or idle penalties.

For heating, Clima-Tech^® manages electric- or fuel-fired auxiliary heaters through the same interface, automatically activating them when engine coolant is unavailable.

Shore Power: Automated Transition

Shore power has always meant separate controls and manual reconfiguration. Clima-Tech^® detects shore power automatically and prioritizes electric heating over fuel-fired alternatives when equipped.

The interface stays the same. Controls, setpoints, and operational logic remain consistent. For fleets with overnight parking facilities or maintenance yards, this means warm cabs at departure, no pre-start idling, and batteries charged for E-Breeze operation.

Unified Diagnostics

The Info button provides real-time system data across all power states: temperatures, pressures, component speeds, and fault conditions. Technicians have the same diagnostic access regardless of whether they are troubleshooting engine-on cooling, engine-off E-Breeze operation, or shore power heating.

Three-tiered fault categorization guides responses:

Red (Non-Operational): immediate attention required
Orange (Non-Recurring): temporary issue, system recovering
Green (Conditional): continued operation with monitoring

This intelligence reduces diagnostic time and enables proactive maintenance, preventing minor issues from becoming major failures.

Why Consistency Matters

Operators learn one interface that works across all power states. Temperature control functions identically. Auto Mode behaves consistently. Manual override stays accessible.

For emergency services, fire apparatus, utility trucks, and commercial fleets, this operational consistency means personnel can focus on their primary work rather than climate management.

Implementation

Clima-Tech^®‘s modular design accommodates varied requirements. Deploy it standalone for engine-on and shore power only or integrate E-Breeze for complete engine-off cooling. The system supports 12V and 24V electrical systems, communicates via CAN bus, and is designed to deliver dependable performance when paired with Simplicity Air’s full range of mobile HVAC components and systems.

Multiple operator interfaces can be installed in a single vehicle when needed, and custom capabilities can be configured through the flexible software platform without specialized hardware.

The Evolution of Mobile HVAC

Idle-reduction regulations, fuel-efficiency mandates, and operator comfort expectations demand more innovative climate solutions. Clima-Tech^® with E-Breeze delivers reduced fuel consumption, decreased idle time, extended component life, simplified training, and improved diagnostics.

By eliminating boundaries between power states, the system provides continuous climate management that adapts transparently to available power sources.
