When cooling requirements go beyond what ducted split systems can handle — the Water Cooled Packaged Air Conditioner steps in as the heavy-duty solution. These high-capacity, self-contained units are engineered specifically for large industrial facilities, commercial complexes, and institutional buildings where powerful, continuous, and highly reliable cooling is a non-negotiable operational requirement.
Everything — compressors, cooling coil, blower, controls, and condenser — is housed within a single robust unit. This all-in-one design simplifies installation, reduces the number of field connections, and makes maintenance more straightforward compared to split configurations. Combined with water-cooled heat rejection, the result is a system that delivers outstanding efficiency and reliability even under the most demanding operating conditions.
Available from 5.5 TR to 16.5 TR — with a maximum cooling output of 198,000 Btu/hr — Water Cooled Packaged units are among the most powerful single-package air conditioning solutions available for commercial and industrial applications. This capacity range is ideally suited for large open-plan production floors, warehouses, auditoriums, hotel ballrooms, data centers, and any space where the heat load far exceeds what smaller systems can handle.
The broad capacity range also allows multiple units to be deployed in parallel across different zones of a large facility — with each unit independently serving its assigned area while sharing the building's common water loop infrastructure. This zoned approach provides both redundancy and operational flexibility that a single large central plant cannot match.
The packaged units support both R22 and R407C refrigerants — giving building owners and facility managers the flexibility to specify R407C for new environmentally compliant installations or maintain compatibility with existing R22 infrastructure where a complete system replacement is not yet practical. R407C is a non-ozone-depleting refrigerant with thermodynamic properties closely matched to R22, making it the most practical transition refrigerant for buildings moving away from older refrigerant technology.
The packaged unit delivers airflow up to 11,210 CMH — Cubic Metres per Hour — or 6,600 CFM. This exceptional airflow capacity enables fast temperature pull-down and effective climate control across very large spaces — including high-bay industrial facilities, large auditoriums, and expansive open-plan commercial floors where the sheer volume of air requiring conditioning presents a significant engineering challenge for smaller systems.
Air movement within the packaged unit is handled by centrifugal double inlet blowers — selected specifically for their ability to generate high static pressure while moving large air volumes efficiently. The double inlet configuration draws air from both sides of the blower wheel simultaneously — increasing airflow capacity without requiring a proportionally larger blower housing. This design delivers the strong, consistent airflow needed to push conditioned air effectively through the duct networks serving large commercial and industrial spaces.
The cooling coil at the heart of the packaged unit uses copper tubes with aluminium fins — a combination that has been the gold standard in commercial air conditioning heat exchanger design for decades. Copper provides excellent thermal conductivity and corrosion resistance on the refrigerant side, while aluminium fins maximize the surface area available for heat transfer between the coil and the airstream. Together, this coil construction delivers high efficiency heat transfer, long service life, and good resistance to the fouling and corrosion that reduce coil performance over time in commercial environments.
Each packaged unit can be equipped with up to three scroll compressors operating in combination. Scroll compressors are the preferred choice for commercial air conditioning at these capacities — delivering higher efficiency, lower noise, smoother operation, and better reliability than reciprocating compressors at equivalent outputs. The use of multiple compressors rather than a single large unit provides an important operational advantage — if one compressor requires maintenance or develops a fault, the remaining compressors continue to provide partial cooling capacity while the issue is resolved, rather than causing a complete system shutdown.
With multiple scroll compressors available, the system implements multi-stage capacity control — matching the total active compressor capacity to the actual cooling demand at any given time. During periods of lower load — early morning, cooler weather, or partial building occupancy — one or two compressors can be staged off while the remaining unit or units continue to operate efficiently. This staging approach prevents the energy wastage of running full compressor capacity when only partial capacity is actually needed, delivering significant energy savings over a typical operating year.
The packaged units require cooling water flow of 20 to 60 US GPM depending on the selected capacity. This water flow is supplied from the building's central cooling water loop — typically served by a cooling tower on the rooftop or an external area. The water loop absorbs heat from the packaged unit condensers and rejects it to atmosphere through the cooling tower, completing the water-cooled refrigeration cycle. Our engineering team designs and sizes the water loop infrastructure as an integral part of every packaged unit project to ensure the system operates within its specified water flow parameters from commissioning onwards.
The packaged units operate on a 380 to 420V three-phase power supply — the standard electrical provision for industrial and large commercial premises across India. Three-phase power is essential at these compressor capacities to ensure smooth, efficient motor operation and to avoid the electrical imbalance problems that would arise from attempting to power high-capacity compressors on single-phase supply. Our installation team handles all electrical connections and verifies supply quality before commissioning.
System operation is managed by an advanced microprocessor-based controller with an LCD display interface. The controller manages compressor staging, capacity modulation, water valve operation, fan speed, temperature regulation, system protection functions, and fault detection — automatically optimizing system operation across varying load conditions without requiring constant manual intervention. The LCD display provides real-time system status, operating parameters, and fault codes — giving building operators and service engineers complete visibility over system performance at all times.
The unit housing is fabricated from heavy-gauge galvanized iron steel with a durable polyester powder-coated finish — engineered for the rigors of industrial and large commercial environments. The GI steel construction provides exceptional structural rigidity and resistance to the mechanical stresses of continuous heavy-duty operation, while the powder coating delivers long-term corrosion protection against the humidity, condensation, and water contact inherent in any water-cooled system installation. This is not a lightweight commercial housing — it is an industrial-grade enclosure built to last.
Every component selection, engineering decision, and construction detail in the Water Cooled Packaged unit reflects its intended role as a continuously operating industrial cooling machine. These units are designed to run for extended daily operating hours, seven days a week, through the long North Indian cooling season — and to keep running reliably year after year with proper preventive maintenance. The multiple compressor configuration, heavy-duty blowers, robust heat exchangers, and industrial-grade housing all contribute to a system with the durability and reliability that industrial and large commercial operators depend on.

Production floors, assembly lines, clean rooms, and process areas in manufacturing facilities require cooling systems that match their scale, reliability requirements, and continuous operating schedules. Water Cooled Packaged units — with their multi-compressor redundancy, heavy-duty construction, and high airflow capacity — are built precisely for this environment. They maintain the stable temperature and air quality conditions that industrial processes and worker productivity both depend on.
Shopping malls, large retail stores, exhibition halls, and multi-purpose commercial complexes need cooling systems that can handle high occupancy loads, variable traffic patterns, and long daily operating hours. The multi-stage capacity control of packaged units allows energy-efficient operation at all occupancy levels — from the quiet early hours to peak weekend trading — without the energy waste of running at full capacity when it is not needed.
Hotel ballrooms, conference centers, large banquet facilities, and resort common areas experience the most extreme load variations of any commercial application — from near-empty to completely packed within a short period. The Water Cooled Packaged unit's multi-stage compressor control handles this variability smoothly and efficiently, maintaining guest comfort throughout while keeping energy consumption in proportion to the actual cooling load.
Universities, government buildings, large hospitals, convention centers, and performance auditoriums all require cooling systems that are powerful enough to handle peak occupancy loads, reliable enough for continuous institutional operation, and efficient enough to manage over long annual operating periods. Water Cooled Packaged units check all three requirements — and their all-in-one construction simplifies the installation and maintenance management that institutional facility teams prefer.
Large data centers and enterprise server rooms generate enormous heat loads that require continuous, reliable cooling with no tolerance for downtime. The multi-compressor configuration of packaged units provides the built-in redundancy that mission-critical cooling applications demand — ensuring that a single compressor fault does not result in complete cooling loss and potential equipment damage in environments where uninterrupted operation is everything.
