LABORATORY TESTING & INSPECTION
Laboratory environmental
control solutions.
Coordinated temperature, humidity, filtration, pressure and ventilation for testing, research and precision laboratory environments.
LABORATORY ENVIRONMENTAL CONTROL
Controlled environments
for reliable laboratory work.
Testing, research, PCR / molecular, chemical and third-party laboratories require stable environments. Heat-generating equipment, volatile substances, biological samples and precision instruments make temperature, humidity, cleanliness, pressure gradients and supply–exhaust balance important to safe operation and reliable results.
Airmaster combines fresh air, air handling, heating and cooling, make-up air, exhaust coordination and intelligent controls around laboratory processes, equipment loads and safety requirements.

Discuss Your Project
Third-party testing
Balance staff comfort, instrument operation, stable temperature and humidity, and room independence.
PCR / molecular laboratories
Coordinate zoning, airflow direction, pressure gradients, cleanliness and fresh-air / exhaust arrangements.
Chemical laboratories
Manage fume-hood and local exhaust loads with make-up air, heating, cooling and stable room pressure.
Microbiology laboratories
Coordinate cleanliness, cross-contamination control, filtration and pressure relationships.
Precision instrument rooms
Limit temperature and humidity fluctuations and support continuous stable operation.
Research / teaching laboratories
Use flexible zoning and energy control for changing experiments and occupancy schedules.
02.2 / CUSTOMER & SCENARIO PAIN POINTS
Laboratory conditions
that must work together.
01
Sensitive experiments
Temperature, humidity and cleanliness fluctuations can affect repeatability and accuracy.
02
Variable exhaust demand
Fume hoods and local extraction require continuous make-up air and stable room pressure.
03
Complex pressure relationships
Sample preparation, clean work, contaminated operations and general analysis require different pressure zones.
04
Changing equipment loads
Long-running instruments generate heat; equipment cycling and occupancy change the cooling load.
05
Independent laboratory systems
Return air and transfer air must account for contaminants, odours and biological risks.
06
Continuous operation
Some laboratories require 24-hour environmental control, status monitoring and accessible maintenance.
02.3 / ENVIRONMENTAL CONTROL REQUIREMENTS
Nine requirements.
One coordinated environment.
Temperature and humidity targets, cleanliness, air-change rates and pressure values must follow local standards, laboratory processes and project requirements.
01. Temperature and humidity
Manage equipment heat gains, room stability, condensation and static-electricity risks.
01
02. Cleanliness and air distribution
Coordinate filtration and airflow to limit dead zones, short-circuiting and cross-contamination.
02
03. Pressure and ventilation
Balance pressure gradients, fresh air, make-up air and independent exhaust.
03
04. Stable, monitored operation
Consider vibration and noise while monitoring environmental conditions, filters and equipment interlocks.
04
From air treatment
to coordinated room control.
Configure the system around laboratory functions, exhaust demand and required environmental precision.
Zoned AHUs
Divide laboratories into independent zones. AAHM-N or DX units combine filtration, cooling, heating, dehumidification, fresh-air treatment and zoned supply.
Air balance
Coordinate make-up air with fume hoods and equipment exhaust to maintain target room pressure. Separate contaminated exhaust as required.
Precision control
Coordinate cooling, reheat, humidification and dehumidification for precision instrument and metrology rooms.
Pressure control
Balance supply, return and exhaust between clean, buffer and contaminated zones, using pressure feedback.
System interlocks
Interlock exhaust, make-up air, dampers and air-conditioning equipment; monitor environmental conditions, filters and faults.
02.5 / SYSTEM CONFIGURATION BY AREA
A configuration framework
for laboratory projects.
| Laboratory area | System configuration approach | Control objectives |
|---|---|---|
| PCR / molecular laboratory | AAHM-N / DX AHU + independent exhaust + pressure monitoring + intelligent control | Zoned pressure, cleanliness, temperature, humidity and supply–exhaust balance |
| Chemical laboratory | Fresh-air / make-up-air AHU + fume-hood exhaust + chiller / heat pump + control | Exhaust balance, negative pressure and sensible / latent loads |
| Microbiology laboratory | AAHM-N + multi-stage filtration + exhaust + intelligent control | Cleanliness, contamination control, pressure and filter status |
| Precision instrument room | Dedicated AHU / DX AHU + precise temperature and humidity control | Environmental fluctuations, equipment heat, noise and stable operation |
| Third-party testing centre | Central chiller / heat pump + zoned AHUs + FCUs + intelligent control | Independent zones, changing loads and overall efficiency |
| Research / teaching laboratory | Modular AHU + FCU / local terminal + central control | Flexible zoning, on-demand operation, fresh air and maintenance |
These configurations are conceptual guidance, not construction designs or final equipment selections. Quantities, capacities, functional sections and control sequences require project design and technical selection.
Environmental control requirements
| Control item | Key requirement |
|---|---|
| Temperature stability | Control fluctuations to suit instruments and experiments while adapting to equipment heat gains. |
| Humidity control | Limit condensation, sample changes and equipment risks; avoid excessively dry conditions and static electricity. |
| Cleanliness | Select filtration and air-cleaning arrangements for the laboratory use and classify critical zones where required. |
| Pressure gradients | Establish appropriate positive or negative pressure relationships between clean, general and contaminated zones. |
| Fresh air and make-up air | Calculate supply for fume hoods, local exhaust and occupancy to avoid loss of room pressure. |
| Exhaust safety | Use independent exhaust for hazardous, odorous or potentially contaminated air, with treatment suited to project requirements. |
| Air distribution | Reduce dead zones and short-circuiting and prevent contaminated air returning to clean or general laboratory areas. |
| Low vibration and stability | Consider air velocity, noise and system stability in precision instrument rooms. |
| Intelligent monitoring | Monitor temperature, humidity, pressure, fans, dampers, filters and alarms with system interlocks. |

The supplied document describes an AAHM-N modular air-handling system with PLC / DDC intelligent controls for a PCR laboratory in Jakarta, Indonesia. The system combines multi-stage filtration, temperature and humidity treatment, pressure monitoring and coordinated supply and exhaust.
Equipment and control
AAHM-N air-handling units, exhaust equipment and fume hoods, variable-air-volume dampers and actuators, pressure sensors, PLC controls with HMI, supply / exhaust filters and duct components form the documented system. Control functions include fan and filter alarms, pressure feedback, closed-loop temperature and humidity regulation, local / remote monitoring and supply–exhaust interlocks.
