BWT filtration, softening, dosing, UV and RO. PLC and HMI panels, BMS and DCIM. Huawei home batteries and PCS, CATL cabinets around 255 to 407 kWh and 20-ft containers near 4 MWh. We also integrate with UPS, ATS and gensets.
Yes, following a site survey and documentation review. We assess safety, firmware versions and parts availability, then propose a plan.
Defined by SLA. Typical is remote triage within four hours during working days and on-site attendance within 24 to 48 hours for priority issues. Critical sites can contract tighter windows.
Yes. We connect via secure VPN or cloud gateways, set points and alarms are agreed, and reports are issued on a weekly or monthly cycle. You keep visibility through a client dashboard.
Yes. We hold common filter media, cartridges, membranes, pump kits, sensors and PLC modules. Battery modules and PCS parts are sourced through authorised channels with expedited logistics.
We maintain sampling plans, logbooks and calibration records. Legionella control for DHW uses temperature regimes and monitored dosing where appropriate, with UV applied on clear water. All actions are traceable for audits.
