COOLMAR CENTRAL HVAC
Fresh-Air and Central Marine HVAC Systems for Larger Projects
Fresh-air treatment, FDU central fan-coil units and PDU central packaged systems are engineered around the vessel’s air volume, cooling and heating loads, filtration, humidity, ductwork and electrical supply. ERBA Marine coordinates the technical enquiry and regional supply scope.
Central systems require load calculations, duct and airflow information, design conditions and suitable machinery-space data.
Fresh air, FDU and PDU
Three project-led routes for ventilation and central vessel air conditioning.
Authorized GCC Dealer
Coolmar product selection and supply coordinated by ERBA Marine.
Project-Led Review
Loads, utilities, space and interfaces checked from verified data.
Newbuild & Retrofit
Support for planned projects, refits and replacement scopes.
Current Configuration
Specifications and warranty terms confirmed in quotation.
Authorized Coolmar dealer for the GCC
ERBA Marine manages regional product selection, technical clarification, quotation and supply for Coolmar marine HVAC and refrigeration equipment.
CENTRAL SOLUTION ROUTES
Separate the air-treatment need from the cooling architecture.
Fresh-air, chilled-water and direct-expansion central packages solve different parts of the vessel HVAC requirement.
Fresh-Air Units
Project-selected outside-air treatment with filtration suited to the operating area.
- Fresh-air volume and filtration
- Cooling, heating and humidity scope
- Duct pressure and installation space
FDU Central Fan Coil Units
Central water-coil air-handling units produced to project requirements.
- Chilled-water or heating-water interfaces
- Project-specific air volume and pressure
- Body and access arrangement confirmed
PDU Central Packaged Units
Central packaged direct-expansion systems produced around the project requirements.
- Cooling and heating scope
- Voltage and regional design conditions
- Air volume, pressure and layout confirmed
ENGINEERING INPUTS
Central HVAC begins with an air and heat-load schedule.
The project team needs zone loads, outside-air demand, duct resistance, design climate, heat sources and operating philosophy before equipment can be sized.
Air-side design
Air volume, pressure and treatment duty define the central unit.
- Outside-air and recirculation quantities
- Filtration and humidity requirements
- Duct resistance and outlet schedule
System-side design
The central package must integrate with vessel utilities and controls.
- Water or refrigerant circuit
- Electrical supply and available power
- Controls, alarms and redundancy
TECHNICAL ENQUIRY CHECKLIST
What to send for a useful HVAC review.
Complete operating, load and interface information reduces unnecessary clarification and helps ERBA Marine prepare a more accurate technical and commercial response.

PROJECT PROCESS
A clear route from HVAC enquiry to coordinated supply.
Marine HVAC selection benefits from documented loads, design conditions and interface checkpoints.
PROCESS
1. Send the project data
Share the vessel, spaces, duty, design conditions, utilities, drawings and required scope.
PROCESS
2. Clarify the interfaces
ERBA Marine identifies missing inputs and checks capacity, space, air, water and electrical interfaces.
PROCESS
3. Confirm the proposal
Configuration, current specifications, documentation, warranty terms, price and delivery are agreed.
PROCESS
4. Coordinate supply
ERBA Marine remains the customer-facing contact through the confirmed supply scope.
Important: Published ranges and examples are selection guidance. Final capacity, dimensions, voltage, refrigerant, materials, controls, documentation, warranty terms, price and delivery are confirmed only in ERBA Marine’s written quotation.
FREQUENTLY ASKED QUESTIONS
Fresh-Air and Central Marine HVAC FAQs
Practical answers for selection, replacement and project planning.
An FDU is a central fan-coil or air-handling unit connected to a water circuit. A PDU is a central packaged direct-expansion air-conditioning unit. The suitable route depends on the overall HVAC architecture.
Yes, subject to project review. Fresh-air quantity, filtration, cooling, heating, humidity, duct pressure and available space must be coordinated with the main system.
They are project-led product families. Coolmar states that body and technical specifications can be modified for the ordered project, so final details require engineering confirmation.
Yes. Send the heat-load schedule, air quantities, design conditions, power supply, duct data, system schematics and machinery-space drawings.
The final requirement may include approved drawings, equipment schedules, interface details, control philosophy and any applicable flag or class documentation.
PROJECT-SPECIFIC ENQUIRY
Request a Fresh-Air and Central Marine HVAC review from ERBA Marine.
Send the strongest available load, space, utility and interface information. ERBA Marine will review the requirement and identify missing data before quotation.
- Attach HVAC drawings, schedules and clear photographs.
- State design air and seawater conditions.
- Confirm voltage, phase, frequency and available space.
- Final scope is confirmed in writing before supply.
