Automation Support
for
Electrical Contractors

We support electrical contractors with industrial control, PLC programming and automation integration services for industrial machinery, process systems and building plant room services.

We are not electrical contractors.

Our role is to provide the control architecture, PLC programming and systems integration that enables industrial automation projects to operate safely, reliably and efficiently. By working alongside electrical contractors, OEMs and project teams we help systems operate correctly, reliably and efficiently.

PLC Automation Control Touch Screen for HVAC

Custom designed and built commercial HVAC load shedding and automation system delivering independent control of 64 heat pumps and 8 intake/extract fans for Building Warrant of Fitness (BWOF) compliance.

A distributed control architecture was implemented using five satellite control panels installed at local distribution boards across the site. Each panel provides localised control, protection, and reliability while maintaining deterministic coordinated system-wide operation.

All panels are networked back to a central custom HMI, providing live monitoring, alarms, operational data, and full system visibility across the entire HVAC network.

Supporting
Electrical Contractors

We work alongside electrical contractors during installation, commissioning and system integration phases to assist with the control aspects of commercial and industrial automation projects and building services automation systems.

This may include:

PLC and HMI development
Integrating third-party equipment
Configuring industrial networks
Commissioning machine sequences
Plant room and HVAC control integration
Troubleshooting comms or control issues
Refining control logic and operation
Assisting with system optimisation and stability

We support implementation — not compete with it.

PLC-based PID heating control system delivered in collaboration with a pool/spa contractor, providing precise and stable temperature regulation.

Includes fail-safe heating valve power-loss closure and auxiliary temperature monitoring for independent verification and fault detection.

Off-Grid Distributed Energy Network – Multi-Dwelling Solar, Battery & Generator System

Solar Multi-generaration and multi-charging PLC Control Panel

Corporate farmstay off-grid multi dwelling development on Great Barrier Island, where distributed PLC-based control systems were used for compound access, integration of accommodation units, water infrastructure, pumping systems, storage tanks, and standby generation into a single networked solution. The system provides reliable RF-to-Ethernet communications for centralised monitoring and control of critical services across the site, with comprehensive alarms, event logging and visibility..

Collaborative
by
Design

Industrial automation and building services projects work best when electrical contractors, mechanical teams and control engineers work together effectively.

We operate collaboratively and professionally throughout implementation and commissioning, with a focus on practical outcomes, technical support and a reliable system.

Commercial
&
Industrial

We support a wide range of automation applications :

Industrial machinery and OEM equipment
Process and production systems
HVAC and mechanical plant rooms
VSD / VFD Pump and utility systems
Ventilation and extraction systems
Water treatment and transfer systems
Distributed building services control
Energy and infrastructure automation

Our focus is always on stable operation, maintainable systems and practical long-term reliability.

Practical Engineering

Good automation should improve reliability, maintainability and operational performance — not create unnecessary complication.

Our approach is based on what will actually work on-site under real operating conditions, not what simply looks good in theory.

We prioritise:

Stable and predictable operation
Maintainable programming structures
Practical diagnostics
Reliable communication between systems
Clean and supportable integration
EMC mitigation measures, including filtering where required, are applied based on drive manufacturer recommendations, cable lengths, installation environment, and system performance requirements.

The goal is simple: deliver control systems that are correctly aligned, reliable and easy to support.
