Uncompromised Uptime for Next-Generation Data Infrastructure

As data processing demands surge across Europe, modern datacenters require cooling infrastructure that combines high density, continuous reliability, and low Power Usage Effectiveness (PUE).

Altop International – as the exclusive partner of Euroclima – provides tailor-made climate systems designed specifically for mission-critical datacenter environments. We combine over 15 years of dedicated datacenter experience with high-tech manufacturing, delivering flexible Air Handling Units (AHUs), modular skid solutions, and pre-programmed datacenter software that perform flawlessly from day one.

Full-Spectrum Scope of Delivery

Design & Spatial Layout

Custom 3D CAD/BIM modelling and AirCalc++ engineering tailored to exact thermal and spatial room constraints.

Emergency Design & Redundancy

Fail-safe control architecture incorporating N+1 or 2N redundancies, rapid restart routines, integrated ATS, and UPS backup power (up to 60s) to ensure zero control downtime.

Modular Skid Units & Package Systems

Off-site manufactured, pre-wired, and pre-piped Skid execution combining Condensing Units (DX/KonAir), dehumidification, and humidification into Lift-and-Plug assemblies.

Plug & Play Integrated Controls

Factory-mounted control cabinets using premium Siemens Climatix, Rittal, and WAGO components. Pre-commissioned software loaded via SD card—no on-site programming required.

Factory Acceptance Testing (FAT)

Comprehensive, optional factory running tests prior to shipment, eliminating surprise risks on site.

On-Site Commissioning (Level 1–4)

Full-lifecycle site testing support:

• L1:Factory acceptance & component verification
• L2:Pre-commissioning & field quality audits
• L3:Functional performance testing
• L4:Integrated System Testing (IST) & handover

Data Center Software & Cloud

Advanced airflow, temperature, and humidity balancing routines with encrypted BACnet / Modbus, SC communication and optional remote predictive maintenance via Climatix IC Cloud.

Heavy-Duty Materials & C4/C5 Protection

Custom casing materials including high-grade stainless steel (AISI 304 / 316L) and C4 or C5 industrial corrosion coatings for aggressive environments.

Complete IT Cooling Chain: From FAU to In-Room FWU

1. Fresh Air Units / Outdoor AHUs (DOAS or FOH)

Fresh Air Pressurization, Free Cooling & Outdoor Conditioning

• Eurovent Certified ZHK INOVA Casing: 50 mm double-walled construction with non-flammable mineral wool insulation (150 kg/m³) delivering Class T2 thermal transmittance and Class TB2 or TB1 thermal bridging.
• Integrated Refrigeration (KonAir / DX):Coordinated inverter-controlled condensing units running on low-GWP refrigerants (R32 / R410A / or others) with zero site refrigerant piping requirements.
• Flexible Heat Recovery: Heat wheels, plate heat exchangers (up to 90% efficiency), or direct free cooling damper control.
• Robust Air Filtration:ISO Coarse to ePM1 filter walls with Filter Safe® leak-proof frames.

2. In-Room Fan Wall Units (FWU)

Precision Cooling Engineered Directly for Server Rack White Spaces

• Active PFC EC Fans:Ultra-low harmonic distortion (THD ≤ 5%) and power factor up to 0.998 for maximum electrical efficiency and grid compatibility.
• Service-Centric Mechanical Design:Hinged, easily removable EC fans, dual-side access doors, quick hydraulic couplings, and top-mounted pipe connections.
• Integrated PICV Valves:Pressure-Independent Control Valves ensure automated hydraulic balancing under variable load conditions.
• High Operational Density:Optimized footprint maximizing kW/m² cooling output inside the server room.

Proven Controls & Cyber Security

• Pre-Loaded Software:Control strategies pre-programmed and loaded via SD card. Simple configuration via display or local web server.
• Inter-Unit Balancing:Autonomous peer-to-peer communication between AHUs balances airflow, temperature, and humidity without single-point-of-failure master controllers.
• Encrypted Cyber Security:Native BACnet SC (Secure Connect), BACnet IP, Modbus IP/RTU, and LON interfaces for encrypted BMS integration.
• Predictive Maintenance Cloud:Climatix IC Cloud access for trend logging, early fault detection, and automated alerts to reduce maintenance overhead.
