National HVLS Engineering & Application Desk
Our HVLS engineering team delivers nationwide destratification and energy analysis support.

Destratification Analysis & Fan Sizing: Provide facility dimensions, ceiling heights, and heating system type; we model thermal stratification patterns, calculate required air circulation volumes, and project annual energy savings from reduced ceiling-to-floor temperature gradients.

HVLS Structural Submittals: Our team generates engineered installation drawings, structural load calculations for existing roof systems, electrical specifications, and energy savings documentation required for utility rebate program qualification.
Large-Diameter Fan Component Logistics
Unlike standard HVAC distributors, ChopAir manages specialized freight for HVLS blade assemblies up to 24 feet in diameter and coordinates delivery schedules accommodating facility operational constraints and installation crew availability.

Installation Crew Coordination: We schedule HVLS fan deliveries synchronized with certified installation teams and facility production shutdowns, ensuring components arrive when overhead crane access is available for safe ceiling mounting operations.

All Super Duty HVLS fans ship with blade airfoil protection, motor assembly cushioning, and hardware organization specifically designed to prevent aerodynamic surface damage and ensure installation-ready condition upon delivery.
