Rawal APR Control:

Variable Capacity performance for new & existing in-place DX systems in a wide range of applications

HVAC reliability & mechanical failures

Mechanical failures are common with any HVAC system, leading to building occupant/tenant discomfort and potentially severe damage to the space and equipment. Once that happens, you may be facing more expensive repairs or entire system replacements, and even loss of productivity from extended downtime.

But you can eliminate the risk of this problem with the APR Control.

Variable capacity enhancement for new and existing HVAC

Rawal APR Control is a variable capacity enhancement for new and existing DX (direct expansion) systems in a wide range of commercial and industrial facilities and applications that helps provide:

  • Tight temperature control
  • Better humidity control
  • Improved high-percentage outside air
  • System protection (fewer emergency calls)

Comfort, Cost-Effectiveness, Simplicity

The Rawal APR Control is a simple add-on device that significantly improves the performance and reliability of your HVAC system while preventing costly mechanical issues.

A cost-effective long-term solution

  • Less expensive than equipment replacement
  • Reduces callbacks 
  • Minimizes risk of interior space damage (water/mold)
  • Keep within annual service/maintenance budget

Consistent and comfortable indoor temperatures year-round without indoor temperature fluctuations or high humidity

Protects refrigeration circuit and compressor by preventing coil freezing and frequent short cycling – reducing service costs and extending equipment lifespan

  • Optimizes HVAC system’s performance, reducing energy consumption and lowering utility bills
  • Reduces or eliminates the need for costly reheat of all types
  • Enables use of variable speed evaporator fans

Prevents system breakdowns: avoid unexpected downtime and disruptions to your facility’s operations

The APR Control is Technician friendly

Rawal Devices provides superior live technical support

Simplified installation/ start-up, and APR Control is virtually maintenance-free

Your in-house or preferred service technicians can get free, live training that fits their schedule

  7. APR Enhances System Reliability

The Rawal APR Control is a variable capacity enhancement to DX HVAC systems.

The dynamic nature of plant growth cycles and cultivation phases demands air conditioning units that can adapt to changing environmental requirements. These HVAC systems play a critical role in maintaining optimal temperature, humidity, and ventilation conditions to support healthy plant development and maximize crop yield.

Industrial manufacturing facilities experience fluctuating occupant loads, demanding robust and adaptable HVAC systems.

The dynamic nature of production processes and workforce activities necessitates air conditioning units capable of adjusting to changing operational demands.

Any commercial retail or office space faces the same challenge – too hot/too cold and too humid being the top complaints. These problems are often driven by varying occupancy across commercial office spaces with  some companies on a regular 5-day in the office schedule while others are on a varied schedule.

The controlled environments within these facilities demand meticulous temperature, humidity, and air quality management. Fluctuating activities, such as experiments or surgeries, necessitate adaptable air conditioning units to maintain optimal conditions.

Restaurants and diners contend with fluctuating occupant loads, demanding adaptable air conditioning (AC) and heat pump (HP) systems. The ebb and flow of customers throughout the day necessitates HVAC units capable of adjusting to changing occupancy levels.

The dynamic nature of healthcare institutions, with varying patient admissions and discharges, requires air conditioning units to constantly adapt to changing occupancy levels. This flexibility is crucial for maintaining a comfortable and healthy environment for patients, staff, and visitors.

Schools face challenges with systems serving classrooms, providing fresh air for a lot of people in a small space.

This often leads to high humidity and equipment failure.
