Custom Fan Coil Units (FCU) – Dedicated Zone Cooling Units

When the ceiling void is too shallow, a riser shaft is too narrow, or an existing opening must be reused, a custom size fan coil unit for restricted ceiling space can be built to fit exact dimensions.

Standard ranges come in fixed steps. Where a 2 ton fan coil unit is too small and a 3 ton fan coil unit is oversized, a custom FCU can be built to match the exact cooling capacity and airflow the space needs.

Longer ducts, extra filters, or multiple outlets need more fan pressure than standard units provide. A custom FCU with the required airflow and static pressure solves this. Units of this kind are sometimes called blower coil units.

Hospitals, pharma facilities, and labs may need higher filter grades, stainless steel construction, and cleanable interiors that standard units do not offer.

Luxury suites, recording rooms, auditoria, and patient rooms often need noise levels below what standard units achieve. A custom acoustic fan coil unit can meet these targets.

Salt-laden coastal air, chemical exposure, or hazardous areas need coated coils, stainless steel parts, or flameproof motors. These are all available in custom-built units.

Casing length, width, and height can be tailored to fit tight ceiling voids, shafts, and recesses. Low profile custom FCUs are ideal where ceiling depth is limited.

Coil rows, fin spacing, and circuiting are engineered for the exact load, water temperatures, and pressure drop. Coils can also be designed for glycol systems where required.

Epoxy, hydrophilic, or other protective coil coatings extend coil life in coastal, industrial, and corrosive environments.

A stainless steel fan coil unit or a stainless steel drain pan FCU improves hygiene and corrosion resistance for healthcare, pharma, food processing, and coastal sites.

High static custom FCUs use larger blowers or EC plug fans to deliver the required pressure for longer duct runs, with better efficiency and control.

Filter sections can be designed for fine (F7) filters, or for HEPA filtration where the application and fan pressure allow.

Acoustic lining, double skin panels, low-speed fans, and vibration isolation create a low noise custom FCU for sensitive spaces.

Hot water coils or electric heaters can be added for heating or reheat, turning the unit into part of a fan coil heating system where needed.

Fresh air connections and mixing box sections allow controlled outdoor air intake directly through the FCU.

Flameproof motors and suitable electrical components can be specified for classified hazardous areas in industrial and chemical plants.

Supply and return air positions can be placed on the side, bottom, rear, or top. Custom FCU spigot positions, including custom supply air spigots and custom return air spigots, are matched to existing ducts and site layouts.

Custom ducted FCUs are built with specific static pressure, spigot sizes, and plenum arrangements to suit the duct network.

Custom vertical fan coil units and custom floor standing FCUs are sized for wall recesses, shafts, or specific floor footprints.

Custom ceiling concealed FCUs, or custom ceiling suspended FCUs, are designed as custom horizontal fan coil units for tight ceiling voids and specific connection positions.

These units feature stainless steel construction, cleanable surfaces, better filtration, and sealed casings for hygiene-critical areas.

Ultra-slim designs deliver the required capacity within very shallow ceiling voids.

A custom 2 pipe fan coil unit provides cooling only, while a custom 4 pipe fan coil unit has separate chilled water and hot water coils for cooling or heating at any time. The 4 pipe system suits hospitals, premium hotels, and process areas needing tight temperature control.

Custom chilled water FCUs connect to a central plant and suit large buildings. Custom DX FCUs work with a condensing unit where no chiller is available.

Our engineers visit the site to measure available space, access routes, existing connections, and site conditions.

We calculate the cooling load, airflow, static pressure, and noise targets to define the custom FCU cooling capacity.

Coil geometry, fin spacing, fan type, and motor are selected for the right balance of performance, efficiency, and noise.

Detailed general arrangement drawings and technical data sheets are prepared, showing dimensions, connections, weights, and performance.

Once drawings and data are approved, the units move into manufacturing, with Compress India coordinating quality and timelines.

Where required, custom FCU performance testing is carried out at the factory to verify airflow, static pressure, electrical safety, and build quality before dispatch.

A custom FCU valve package with two-way valves or a PICV custom FCU setup supports variable flow systems. A custom FCU with a PICV valve package delivers stable temperatures and easy balancing.

Three-way valves maintain constant system flow by bypassing water around the coil when cooling is not needed.

Thermostats with multi-speed or variable speed fan control provide accurate room comfort.

Custom BACnet FCU or custom Modbus FCU controllers allow a custom fan coil unit with BMS integration, enabling central monitoring, scheduling, and alarms.

A custom FCU with an EC motor, or a BLDC custom FCU, uses significantly less fan energy and allows precise airflow tuning.

Coils designed for a higher chilled water temperature difference reduce water flow and pumping energy across the building.

Lower resistance filters and coils reduce the fan power needed for the same airflow.

Two-way valves and PICVs enable variable flow chilled water systems. Together, these features create an energy efficient custom FCU system.

Units are built to exact dimensions, fitting spaces where standard units simply cannot go.

Capacity, airflow, and static pressure are engineered for the space, avoiding oversizing and undersizing.

Acoustic construction and special filtration deliver quieter operation and cleaner air.

Coated coils, stainless steel, and specialised components extend service life in coastal and industrial sites.

A custom replacement fan coil unit for an existing installation can match old dimensions and connections, avoiding costly civil and piping changes.

Custom units allow a uniform design, connection standard, and control approach across all floors and zones.

Engineering, special materials, and smaller production runs make custom units more expensive than catalogue models.

Design approval and manufacturing take longer than supplying stock units.

Critical spares should be planned and stocked in advance for long-term support.

Accurate site data and timely drawing approvals are essential to avoid delays.

Compress India manages design, approvals, lead times, and spare parts planning, so these limitations are handled smoothly.

Low-noise, low-height custom FCUs suit guest suites, villas, and premium apartment fan coil units where interior design leaves little ceiling space.

Hygienic stainless steel FCUs with better filtration serve patient rooms, clinics, and treatment areas.

Custom FCUs with special filtration, stainless steel construction, and precise control support regulated environments.

Custom units deliver high sensible cooling and reliable airflow for equipment rooms.

Flameproof motors, coated coils, and robust casings suit industrial and chemical plants.

Anti-corrosion coatings and stainless steel components protect units from salt-laden air in coastal buildings.

Custom dimensions allow central cooling in buildings where standard units cannot fit without altering the structure.

A retrofit fan coil unit built to match the old unit's size and connections makes replacement quick and minimally disruptive.

Filters are cleaned or replaced at defined intervals based on filter type and site conditions.

Scheduled fan coil unit cleaning of the coil and fan restores cooling performance and reduces energy use.

Drain pans and drain lines are cleaned and sanitized to prevent blockages, odours, and microbial growth.

Valves, actuators, thermostats, and BMS controllers are checked for correct operation.

We maintain records of each custom design and plan critical spares, such as motors, fans, filters, and actuators, for quick replacement.

• Comprehensive AMC: Covers scheduled maintenance plus specified spare parts, with predictable annual costs.
• Non-Comprehensive AMC: Covers scheduled maintenance and service visits, with spare parts charged separately.

Causes: inaccurate load data or changes in room usage.

Solution: Recheck the heat load, verify water flow and temperatures, and modify or upgrade the coil if needed.

Causes: clogged filters, undersized ducts, or incorrect fan selection.

Solution: Clean filters, review the duct design, and adjust or upgrade the fan.

Causes: blocked drains, wrong slope, or incorrect trap height.

Solution: Clean the drain, correct the slope and trap, and inspect the drain pan.

Causes: high fan speed, worn bearings, or missing isolation.

Solution: Adjust fan speed, replace bearings, and add or repair vibration isolation.

Causes: coastal air, chemicals, or lack of protective coating.

Solution: Clean the coil, apply protective coatings, or replace it with a coated or upgraded coil.

Causes: wiring faults, failed actuators, or controller issues.

Solution: Repair wiring and replace faulty actuators or controllers.

Unit size, coil rows and coatings, fan and motor type (standard, EC, or flameproof), stainless steel construction, filtration grade, and acoustic treatment all affect the price.

A custom FCU typically costs more than a standard fan coil unit of similar capacity. In return, it avoids costly civil changes, improves performance, and lasts longer in demanding conditions, which often makes it the better long-term investment.

Rigging, supports, piping, valve packages, ductwork, drains, electrical work, and commissioning make up the installation cost.
