Snowfairy Ultra-Low Temperature Inverter Heating & Cooling Integrated Unit: Powerful, Reliable, and Quiet Performance for All Climates

Product Overview

The Snowfairy Ultra-Low Temperature Inverter Heating & Cooling Integrated Unit is a cutting-edge solution designed to deliver exceptional heating and cooling performance even in extreme cold environments. As part of our premium product lineup, this series combines advanced technology, robust engineering, and user-centric design to meet the rigorous demands of residential and commercial applications—particularly in northern regions requiring reliable winter heating and hot water.

Core Features

1. Unmatched Low-Temperature Operation

Equipped with an industry-leading ultra-low temperature DC inverter compressorand low-temperature gas injection superheat technology, this unit guarantees stable operation at temperatures as low as -35°C. This breakthrough ensures uninterrupted heating and hot water supply during harsh winters, a critical advantage for cold-climate regions.

2. Powerful Heating for Northern Winters

Leveraging its optimized heat exchange system, the unit delivers robust heating capacity in sub-zero conditions. It effectively meets the dual needs of winter space heating and domestic hot water, ensuring comfort and convenience even when outdoor temperatures plummet.

3. Integrated, Noise-Reduced Design

Featuring a sleek, space-saving integrated structure, the unit minimizes installation complexity while maximizing efficiency. Advanced noise-reduction technologies—including silent fans and vibration-dampening components—ensure whisper-quiet operation, enhancing user comfort in both residential and commercial settings.

Performance Under Diverse Conditions

The unit maintains high efficiency across varying operating environments, ensuring consistent performance:

Standard Heating: At 7°C dry-bulb / 6°C wet-bulb ambient temperature, it delivers 40°C inlet water to 45°C outlet water.
Low-Temperature Heating: Even at -12°C dry-bulb ambient temperature, it achieves 41°C outlet water temperature.
Cooling Mode: At 35°C dry-bulb / 24°C wet-bulb ambient temperature, it cools 12°C inlet water to 7°C outlet water.

Note: Unit capacity varies with ambient temperature. For precise project planning, consult our technical engineers. Actual machine nameplate parameters prevail in case of product improvements.

1. Partnership & Procurement Assurance – Ensuring Project Certainty

(1) OEM/ODM Production Stability & Lead Time
Snowfairy operates a modern 50,000 m² manufacturing base in Wuzhi County, Jiaozuo City, equipped with automated production lines and multiple environmental test chambers (including ultra-low-temperature labs). We guarantee stable mass production capacity with an annual output exceeding 50,000 units across all heat pump series. Standard lead time is 30–45 days after order confirmation, with expedited options available for urgent projects.

(2) Customization Capabilities
Beyond standard model selection, Snowfairy offers flexible customization to meet diverse market requirements:

Electrical Configuration: Voltage (220V/380V/400V/480V), frequency (50Hz/60Hz), and phase (single/three-phase) adaptation.
Aesthetic & Branding: Cabinet color customization (RAL code accepted), OEM/ODM branding (logo engraving, custom nameplates, packaging design).
Environmental Adaptation: Units can be engineered for high-altitude (>3,000m), high-dust, high-humidity, or coastal saline environments with enhanced corrosion protection (e.g., Blue Fin condenser coils, IP55-rated electrical enclosures).

(3) Payment & Logistics Terms

Payment Methods: T/T (30% deposit, 70% before shipment), L/C at sight, D/P negotiable for long-term partners.
Trade Terms: FOB Qingdao/Ningbo, CIF/CIP to global ports.
Logistics Support: We partner with major forwarders (DHL, Kuehne+Nagel, COSCO) to provide door-to-door sea/air freight solutions. For emerging markets (e.g., Southeast Asia, Middle East, Latin America), we offer DDP/DDU options and assist with customs documentation, local compliance, and import duty estimation.

2. Technical Integration Support – Reducing Installation & Commissioning Costs

(1) Comprehensive Documentation (Free & Multilingual)
All products include:

English installation & operation manuals
