LS Electric H100 HVAC Inverter

The LS Electric H100 is a dedicated variable frequency drive engineered specifically for HVAC, building services, and water system applications in Saudi Arabia's commercial and industrial construction sector. Covering 0.75 kW to 75 kW on 380–480 V three-phase supply, the H100 delivers optimised performance for centrifugal fans, axial fans, chilled water pumps, condenser water pumps, cooling tower fans, and AHU drives in the towers, hospitals, hotels, and government buildings that define the Kingdom's rapidly expanding built environment. The H100 is built with a dedicated HVAC application firmware that pre-loads all the control parameters, protective functions, and communication configurations most commonly required in building services — reducing on-site commissioning to under 20 minutes for standard fan and pump duties. An integrated BACnet MS/TP communication port is standard on all H100 units, allowing direct connection to Johnson Controls, Siemens Desigo, Schneider EcoStruxure, and other major BMS platforms without optional cards.

The H100's technical highlights include a PID sleep/wake function that shuts down the drive during periods of very low demand and restarts it automatically when process pressure drops — reducing energy consumption and drive wear in overnight building operation cycles. Automatic energy-saving mode (AES) continuously optimises motor voltage to minimise losses during part-load operation, delivering additional savings beyond simple fan law energy reduction. Fire mode enables the drive to run at a fixed speed regardless of fault conditions, supporting smoke extraction and emergency ventilation requirements in fire safety systems as required by Saudi Civil Defence regulations. The drive operates continuously at 50°C ambient without derating, essential for Saudi Arabia's mechanical plant rooms which routinely exceed 45°C during peak summer.

The H100 is specified in HVAC projects across the Kingdom by Saudi Aramco facilities management, hospital operators under the Ministry of Health, hotel chains developing assets for Vision 2030 tourism targets, and government facility management companies. It is increasingly preferred over European HVAC drives by Saudi MEP contractors for its competitive SAR pricing, strong BACnet integration, and local LS Electric technical support through Razz Middle East. The drive carries CE, KC, and UL certifications, and meets ASHRAE 90.1 motor drive efficiency requirements relevant to LEED and Estidama green building ratings.

Razz Middle East stocks the H100 across all common power ratings for same-week delivery to Saudi Arabia. We offer pre-configured BMS parameter templates for major HVAC system integrators, reducing project commissioning time and cost. Our HVAC drive specialists provide technical support in Arabic and English, covering BACnet addressing, PID tuning, and fire mode configuration for Code-compliant installations.
