Creating accurate and detailed quotations for Air Handling Units (AHUs) can be a complex, time-consuming task. From selecting the right components to ensuring compliance with standards like HTM, the traditional quoting process often involves multiple calculations, extensive manual work, and a high risk of errors.

This is where Rubix, the Controls Selection Tool by iACS, revolutionises the process. Designed to simplify and speed up AHU quoting, Rubix combines intelligent automation with user-friendly features, helping engineers and project managers save time, reduce mistakes, and deliver precise quotes with ease.

This guide dives into how Rubix works, why it's the superior solution for AHU quotations, and the benefits it brings to your projects.

The Problem with Traditional AHU Quoting

The quoting process for AHUs has traditionally been a manual and tedious task, often involving:

Extensive Calculations: Determining the correct size, type, and configuration for every component.
Repetitive Work: Entering similar details repeatedly for units with slight variations.
High Error Risk: Missing details or miscalculating specifications can result in delays or costly mistakes.
Inefficient Documentation: Creating branded, professional quotes and data sheets adds another layer of complexity.

These challenges make traditional quoting both time-intensive and prone to inefficiencies.

How Rubix Transforms the Process

Rubix eliminates these inefficiencies by providing:

Automated Calculations: Intelligent algorithms handle complex component sizing and configurations.
Pre-Configured Defaults: For common requirements like HTM-compliant panels, saving time and ensuring accuracy.
Customisation Options: Tailor components and layouts to meet project-specific needs.
Instant Documentation: Generate branded quotations and data sheets in seconds.

Rubix is not just a tool—it’s a game-changer for HVAC professionals.

Step-by-Step Guide to Using Rubix

Step 1: Access the Rubix Dashboard

Navigate to the dashboard, where all your projects are displayed.
Click "Add New Unit" to create a new project.
Assign a project name, such as "AHU1," for easy identification.

Step 2: Define Initial Project Details

Select the Unit Type: Choose "AHU" or other systems as required.
Choose the Panel Type:
- Standard Panels for general use.
- HTM-Compliant Panels for healthcare projects.

Step 3: Configure Components

Rubix walks you through each component with automated recommendations:

Filters: Select types (bag, panel, or HEPA filters) and configure differential pressure alarms.
Fans: Specify fan quantity, motor type (e.g., EC or AC), and add inverters for efficiency.
Dampers: Input dimensions and select actuators with appropriate IP ratings.
Coils: Define heating or cooling coils (LPHW, DX, or electric) with flow rate and voltage.
Humidifiers: Choose models (isothermal, DX, etc.) and add features like humidistats.
Heat Recovery Systems: Select thermal wheels, plate exchangers, or runaround coils.

Step 4: Customise the Control Panel

Choose enclosure types, power supply options, and wiring configurations.
Add internal lighting or anti-condensate heaters as required.

Step 5: Review and Export

Review the cost breakdown and component summary.
Export branded quotations and data sheets in PDF format.
