Kiriazi 6‑Drawer No‑Frost Upright Freezer: Complete Technical and Service‑Level Overview

The Kiriazi KH256VF / UGH0044N 6‑drawer no‑frost upright freezer combines 270‑liter capacity, tropical hermetic compressor and digital control, making it a solid choice for hot‑climate households and technicians who need clear service data. Below is a full, technician‑oriented specification including compressor capacity, wattage, capillary estimates and oil characteristics.

Main cabinet specifications

Item	Specification
Brand / model	Kiriazi KH256VF / UGH0044N upright deep freezer
Type	Freestanding vertical no‑frost freezer, 6 drawers
Gross / net capacity	Around 270 liters total storage
Drawers	6 storage drawers + extra ice/fast‑freeze compartment
Dimensions (W × D × H)	62 × 67 × 163.6–164 cm
Cooling system	Forced‑air evaporator, automatic no‑frost fan system
Features	Fast‑freeze mode, digital display, open‑door alarm, info labels per drawer
Insulation	High‑efficiency polyurethane, thickness about 8–10 cm

Electrical and performance data

Parameter	Value
Power supply	220 V, 50 Hz ±10%
Compressor capacity (ASHRAE 23.3 °C)	156 W tropical hermetic compressor
Approx. compressor hp class	≈ 1/6 hp low‑back‑pressure, typical for 250–270 L upright freezers
Cooling rating	3–4 star freezing performance
Monthly energy consumption	About 34 kWh/month, high‑efficiency class for its segment
Energy‑saving features	Thick insulation, fan stop when door opens, optimized air circulation

The 156 W ASHRAE rating places the compressor firmly in the 1/6 hp category, widely used for domestic vertical freezers because it balances pull‑down speed with low running consumption.

Refrigeration circuit: refrigerant, capillary and oil

Official retail pages specify cabinet and compressor wattage but not full circuit details; the following values combine what is published for KH256VF with standard practice for similar Kiriazi no‑frost systems.

Component	Typical data for KH256VF‑class unit
Refrigerant	R134a, used widely in Kiriazi domestic uprights of this size and period
Estimated refrigerant charge	Approx. 120–150 g R134a (230 L Kiriazi uprights use ≈120 g; 270 L models usually fall slightly higher)
Expansion device	Capillary tube feeding a forced‑air evaporator (no‑frost)
Practical capillary range (service reference)	Internal diameter about 0.7–0.8 mm with 2.5–3.0 m length for 1/6 hp R134a low‑temperature application; exact factory size is not published and should be copied from the original tube when available.
Compressor type	Tropical hermetic LBP compressor, designed for high ambient temperatures
Recommended oil type	POE (polyolester) oil for R134a domestic compressors, viscosity ISO 22–32
Typical oil quantity	Around 200–300 ml for 1/6 hp hermetic can, exact value depends on compressor model plate

Because Kiriazi does not publish a full service manual online for KH256VF, technicians should always read the information on the compressor nameplate first (refrigerant, oil type, charge) and then use these ranges only as a backup or design reference.

Practical service notes for technicians

When replacing a compressor, match hp class (1/6 hp LBP), refrigerant (R134a) and voltage (220 V, 50 Hz), and choose a tropicalized model to handle hot Tunisian and Egyptian conditions.
If the original capillary tube is damaged, the safest procedure is to reproduce its exact length and internal diameter; if this is impossible, start within the 0.7–0.8 mm × 2.7 m range and fine‑tune by observing suction pressure, amp draw and pull‑down time in accordance with standard commissioning practice.
Always evacuate to deep vacuum and weigh in the charge whenever the system is opened, especially with POE oil, which is highly hygroscopic and sensitive to moisture contamination.

This table‑driven overview gives a field‑ready technical picture of the Kiriazi 6‑drawer no‑frost upright freezer, allowing you to plan repairs, retrofits or comparative evaluations with similar vertical deep‑freezer models.
